This unexpected fact for a field such as astrophysics arises from the difficulty of detecting Sun-like stellar winds. Their detection relies on the appearance of an astrospheric signature (from the stellar wind-ISM interaction region), visible only with the aid of high-resolution HST Lyman-alpha spectra. However, observations and modelling of the present day Sun have revealed that magnetic fields constitute the main driver of the solar wind, providing guidance on how such winds would look like back in time. In this context we propose observations of four young Sun-like stars in order to detect their astrospheres and characterise their stellar winds. For all these objects we have recovered surface magnetic field maps using the technique of Zeeman Doppler Imaging, and developed detailed wind models based on these observed field distributions. Even a single detection would represent a major step forward for our understanding of the history of the solar wind, and the outflows in more active stars. Mass loss rate estimates from HST will be confronted with predictions from realistic models of the corona/stellar wind. In one of our objects the comparison would allow us to quantify the wind variability induced by the magnetic cycle of a star, other than the Sun, for the first time. Three of our targets are planet hosts, thus the HST spectra would also provide key information on the high-energy environment of these systems, guaranteeing their legacy value for the growing field of exoplanet characterisation. ------------------------------------------------------------------------------------ 15299( 14) - 10-Jan-2019 20:21:48 - [ 2] Observations Description ------------------------ Primary Objective: Our primary goal is to measure stellar mass loss rates by accurately modelling the observed astrospheric Hi absorption in the Lyman-alpha line of four young Sun-like stars (iota Horologii, HD1237, HD147513, HD190771; S. Types: G0V to G8V; Ages: 400 to 880 Myr). Generalities: The measurement of solar-type winds is only possible with the unique capabilities of HST/STIS. The sole transition in which the astrospheric boundary is detectable is Lyman-alpha at 1215.6 Angstroms. Also the interstellar column density must be moderately low (i.e., log N(H I) < 18.4), in order that the saturated ISM H I absorption does not overlap with the astrospheric signal. Practically all resonance lines strong enough to be sensitive to such low ISM column densities are in the UV. The high spectral resolution capabilities of STIS are critical for the measurement of astrospheric structure. This requires the determination of ISM cloud properties (e.g., velocity, temperature), so an accurate absorption line profile can be determined (Redfield & Linsky 2008). Only STIS has the high spectral resolution capability to resolve closely spaced ISM absorption profiles (such as for Mg II in E230H; R ~ 110000) or astrospheric absorption from interstellar absorption (as well as D I from H I in E140M; R ~ 45800). Observing Strategy: We propose to use the high resolution E230H grating to observe Mg II and Fe II. These "heavy" ions are not significantly broadened thermally, and provide sharp line profiles to resolve the velocity structure of the ISM along the line of sight. Because the hydrogen at the astrospheric interface is hot (T ~ 100000 K), it has a broad absorption profile, and does not necessarily require high spectral resolution. Therefore, to maximize S/N, we plan to use the E140M setting. Due to the wide spectral range of STIS, we would obtain practically the entire far-UV band (from 1150-1700 Angstroms) and several more ISM absorption lines (e.g., D I, C II, N I, O I, Si II, Si III, Al II) in addition to Lyman-alpha. With the defined velocity structure by Fe II and Mg II, we could also use all of these lines (Redfield & Linsky 2004). After acquisition, peakup, and observational overheads are considered, we expect at least 28 minutes to be available in the first orbit for the E230H exposure. This provides time to attain very high S/N > 50 at the half-maximum (that is, one half FWHM from the line center, because it is unlikely that the ISM absorption will be centered at the same velocity as the star) of the strong Mg II lines. These S/N levels allow for the detection of weak column densities (log N(Mg II) ~ 11.0), even in blended profiles (demonstrated in Redfield & Linsky 2002). After acquisition and overheads are considered, we expect at least 41 minutes of exposure time to be available in the second orbit for the E140M exposure, and 48 minutes in subsequent orbits. To obtain a S/N > 30, which is required to model the Ly-alpha profile (see Wood+2005a), 3 orbits are required. Timing Constraints: The narrow apertures available with STIS are likewise required to minimize the 15299( 14) - 10-Jan-2019 20:21:48 - [ 3] contamination of the geocoronal emission line in Lyman-alpha, and allow for an accurate astrospheric measurement. We require a minimal timing constraint to ensure that the geocoronal line is well within the saturated core of the broad ISM Lyman-alpha absorption. This has been taken into account in the visit planner for each target. Brightness limits: All of our stars have UV spectra characterized by minimal continua, but strong emission lines. For this reason, they fall far short of the global brightness limit. The emission lines also fall far short of the local brightness limit. The two emission lines of interest in this proposal (Lyman-alpha and Mg II) are also the brightest, and therefore, the procedure for estimating the S/N near their peaks is also used to test for brightness limit violations. For the E230H, the local count rate is 20x lower than the limit and 10x lower than the global count rate limit. There is a reduced contribution from the continuum in the E140M setting so the observations are well below the local and global limits. Notes regarding the Phase II preparation: 1. According to the acceptance letter, we were granted 13 orbits for cycle 25 and 2 orbits for cycle 26. As part of the preparation of the Phase II of our program, we realized that it would greatly benefit the science case by moving 1 of the allocated orbits of cycle 25 to be used during cycle 26. This means that we only use 12 orbits during cycle 25 and 3 orbits during cycle 26 (using the same amount of orbits in total). The reason behind this change is connected with one of the objectives of our program, which is to determine if there is a detectable change in the mass loss rate over the course of a stellar activity cycle (performed in one of our targets, iota Horologii). That is the reason why we requested a certain amount of orbits for the upcoming cycle. However, in our initial Phase I estimation, we neglected possible variations that may occur in the local interstellar medium (ISM) during this time. Nevertheless, to avoid possible ambiguities in the interpretation we would perform local ISM diagnostics during each visit, for which one extra orbit is required for cycle 25. This orbit has been be removed from the original Phase I request of one of our other targets (HD147513), from which we would still attain the required S/N levels for our science measurements according to various calculations of the STIS/ETC. This change was requested and approved by the Telescope Time Review Board (TTRB), under the Change Request Number 88432. 2. For one of our targets (HD147513) the Bright Object Tool (BOT) showed some Health/Safety flag regarding the local and global count rates. However this is due to the fact that the software is misidentifying the spectral type of our target star (G5V), which is well know from the literature (see Hussain et al. 2016 and references therein), for an O5V star. Apart from our target star, there are no other objects identified by the BOT in the observed field. ------------------------------------------------------------------------------------ 15299( 14) - 10-Jan-2019 20:21:48 - [ 4] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 IOT-HOR STAR, EXTRA-SOLAR RA=02H42M33.1600S +/- 0.01", J2000 V = V = 5.40 +/- 0.02 TYPE=G0V, B-V=0.561, PLANETARY SYSTEM, G DEC=-50D48'3.00" +/- 0.01" 16.943 E(B-V)=0, F-LINE(2796)=4.02E-12, V-IV W-LINE(2796)=0.6, F-LINE(1216)=2.86E-12, W-LINE(1216)=0.7 Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
