Linsky University of Colorado at Boulder N CoI: Dr. Seth Redfield Wesleyan University N CoI: Dr. Brian Erland Wood Naval Research Laboratory N ------------------------------------------------------------------------------------ Abstract H I Lyman alpha (LyA; 1216 A) is the brightest emission line in the UV spectrum of F-K dwarfs and is as bright as the rest of the entire 1150-3000 A emission from M dwarfs. Stellar LyA emission plays a critical role in the chemistry of exoplanet atmospheres, energy transport in the stellar chromosphere, and in probing the density structure of the ISM. Thus, accurately characterizing LyA is critically important. However, interstellar H I removes more than 50% of the stellar LyA flux even for the nearest stars, necessitating reconstruction from the observed line profile wings and an assumption concerning the shape of the line core. The Sun (a G2 dwarf) is the only star for which we have high-resolution direct observations of the line core shape, which is self-reversed. Self-reversal in the LyA line core likely depends on spectral type, so incorrect assumptions of the line core shape for stars cooler or more active than the Sun will result in erroneous intrinsic LyA fluxes. We propose to directly measure with high spectral resolution (STIS E140M) the LyA line cores of five high radial velocity stars (G8 V to M4 V). These will be the first measurements of the LyA line with large Doppler shifts and sufficient resolution to probe the LyA line core shape. We will quantify the self-reversal depth, width, and symmetry, and compare amongst the spectral types. STIS E230H spectra will measure the Mg II line core shapes to test whether they are a good proxy for the LyA core shape. This program will create the first publicly available LyA intrinsic profile templates for late-type stars and update widely-used stellar LyA databases like the MUSCLES Treasury Survey. ------------------------------------------------------------------------------------ Observations Description ------------------------ The target list is composed of nearby (< 6 pc), high radial velocity (> +/-80 km/s) G, K, and M dwarfs. These targets will allow us to measure the shapes of the H I LyA (1216 A) and Mg II (2798, 2802 A) line cores as the line cores are Doppler shifted away from the interstellar H I and Mg II absorption and the geocoronal H I emission. To observe H I LyA (1216 A), we will use the STIS E140M grating with the narrow 52" x 0.05" slit to minimize geocoronal LyA contamination and separate the line core from the ISM absorption trough. We will also use the STIS E230H grating with the 0.2" x 0.2" slit to measure the Mg II (2798, 2802 A) line cores. All of these exposures will be obtained in time-tag mode to identify any flares. 15190( 9) - 18-Oct-2019 19:57:40 - [ 2] Our sample includes two late G/early K type dwarfs, and three early-to-mid M dwarfs, including Barnard's Star (GJ 699), the 4th closest star to the Earth, and GJ 411 (HD 95735), the 6th closest star to Earth. This five-member sample spans G, K, and M spectral types to elucidate any dependence in the line core shapes on spectral type (this is expected to depend on the stellar surface magnetic fields). Each of our five targets has its own visit. No visit has more than 4 orbits, and we have elected to obtain all of our LyA and Mg II observations contemporaneously as we are seeking correlations between these line core shapes and the shapes may vary on longer time scales with stellar activity/variability. Exposure time calculations for the LyA observations (STIS E140M) were carried out using known or estimated fluxes, and in the case of Kapteyn's star (HD 33793), a fit to the COS G130M archival observation. Kapteyn's star (M1 V) and GJ 783A (HD 191408; K2.5 V) have archival Mg II (STIS E230H) observations, and this data was used in the ETC. For the remaining three stars (a G8 V, M2 V, and M4 V) without archival Mg II observations, we scaled the Mg II fluxes to match the appropriate distance and to correspond to approximately the appropriate spectral type. ------------------------------------------------------------------------------------ 15190( 9) - 18-Oct-2019 19:57:40 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 HD-33793 STAR, EXTRA-SOLAR RA=05H11M40.5811S, J2000 V = V = 8.853 PLANETARY SYSTEM, M DEC=-45D01'6.29" 245.19 V-IV Reference Frame: ICRS Extended: NO Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2000 0.6135020248160901 -5.73084 0.25566 ------------------------------------------------------------------------------------------------------------------------------------ 3 -E-ERI STAR, EXTRA-SOLAR RA=03H19M55.6509S, J2000 V = 4.27 PLANETARY SYSTEM, G DEC=-43D04'11.22" V-IV Reference Frame: ICRS Extended: NO Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.

The original ETC run is still listed (for 497 s). The ETC was updated to include a Kurucz spectral model of an early M dwarf, but this did not significantly change the output. ------------------------------------------------------------------------------------------------------------------------------------ Sub Exposures ------------------------------------------------------------------------------------------------------------------------------------ Target | Exp |Instr | Oper. | Aper |Spectral|Cent.|Primary |Secondary |Iteration |CR-SPLIT |Orbit |Duration Name | Num |Config | Mode | or FOV |Element |Wave.|Pattern Pos |Pattern Pos |Num |Num |Number | ------------------------------------------------------------------------------------------------------------------------------------ HD-95735 1 STIS/CCD ACQ F25ND3 MIRROR none none none none 1 N/A HD-95735 2 STIS/CCD ACQ/PEA 0.2X0.05 MIRROR none none none none 1 N/A K ND HD-95735 3 STIS/FUV TIME-TA 0.2X0.06 E140M 1425 none none none none 1 1807.0 S -MAMA G HD-95735 4 STIS/FUV TIME-TA 0.2X0.06 E140M 1425 none none none none 2 2868.0 S -MAMA G HD-95735 5 STIS/FUV TIME-TA 0.2X0.06 E140M 1425 none none none none 3 2868.0 S -MAMA G HD-95735 6 STIS/FUV TIME-TA 0.2X0.06 E140M 1425 none none none none 4 1927.0 S -MAMA G HD-95735 7 STIS/NUV TIME-TA 0.2X0.2 E230H 2713 none none none none 4 438.0 S -MAMA G 15190( 9) - 18-Oct-2019 19:57:40 - [ 14] Visit: 06 (GJ 411 E140M redo) Visit Requirements: On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 HD-95735 STIS/CCD ACQ F25ND3 MIRROR 1 0.1 S (0.1 S) ------------------------------------------------------------------------------------------------------------------------------------ 2 HD-95735 STIS/FUV TIME-TA 0.2X0.2 E140M 1425 BUFFER-TIME=2000 1 2260 S -MAMA G (2260 S) Comments: Changed to the 0.2"x0.06" slit to avoid order overlap in echelle mode.
