This focus stresses the need for a comprehensive understanding of the radiation environments in which such planets reside. Low-mass stars are typically much more active than solar type stars and the proximity of their habitable zones can be one tenth the distance. The far-ultraviolet (FUV) radiation emitted by these stars has the potential to alter an orbiting planet's atmospheric photochemistry, while the extreme-ultraviolet (EUV) radiation can cause the loss of planetary atmospheres and surface volatiles. Ly-a emission at 1216 A is the dominant radiation source for low mass stars at FUV wavelengths and is critical for informing stellar atmosphere models used to predict the EUV spectrum, but directly measuring a low-mass star's Ly-a emission is almost always impossible because of the contaminating effects of interstellar hydrogen. Using Gaia DR2, we have identified a unique sample of six low mass stars for which a complete and accurate measurement of their Ly-a line profile is possible due to their very large radial velocities. Stars with very large radial velocities (>100 km/s) will have their Ly-a emission Doppler shifted away from contaminating sources allowing for the rare opportunity to measure intrinsic Ly-a emission. These proposed observations of this rare sample of stars will triple the number of stars with Ly-a emission measured in this way and will improve the accuracy of computed spectra for all low-mass stars across wavelengths that drive planetary atmospheric evolution. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will use HST/STIS to observe unobstructed Lyman-alpha emission from six low-mass stars (HD 64090 (K0), HD 134439 (K1), HD 134440 (K2), HIP 117795 (K8), Ross 451 (M0), L 802-6 (M3)) with large radial velocities (> 100 km/s). For each target we will first perform a STIS target acquisition sequence (ACQ/SEARCH and ACQ/IMAGE), which take seconds. We will then use the STIS/G140M grating to observe the Lyman-alpha wavelength region with the 52"x0".1 slit centered at 1222 Angstroms. These settings have been used successfully in the 16646( 4) - 02-Mar-2022 15:31:55 - [ 2] past for similar observations of high radial velocity M and K dwarfs. All of our targets are field-age or older dwarf stars, and should thus be considered inactive stars with low probabilities of flaring events that could potentially harm the STIS detector. Our estimated count rates for all targets are well below any overlight limits for STIS. In response to the Bright Object Protection Considerations for M Dwarf Flare Events HST Instrument Science Report (Osten 2017), we evaluated the possibility of a destructive flaring event for our two inactive M dwarfs. Following the steps outlined in the ISR, we find global and local count rates less than the detector limits for a simulated flare for both spectroscopic and target acquisition observations. These targets are thus safe to observe with STIS. Further, because our targets are all field age or older, they are likely to have spun down, with rotation periods of 10s of days, much longer than our proposed observations. Therefore, rotational variability should have little effect on the observed Lya fluxes. ------------------------------------------------------------------------------------ 16646( 4) - 02-Mar-2022 15:31:55 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 HD-64090 STAR, K III-I RA=07H53M33.1187S, J2000 V = 8.25 NUV=12.79, FUV=21.04 DEC=+30D36'18.26" Reference Frame: ICRS Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.This object was generated by the targetselector and retrieved from the SIMBAD database.
