Both wavelength regimes (far-UV with HST, X-rays with XMM) are needed to constrain models sufficiently to represent realistic conditions. An approved TESS program for our targets will provide additional information on surface inhomogeneities (spots) and their sizes and locations so that that can be taken into account as well. The FUV and X-ray fluxes from young stars are erosive of a planet's atmosphere, particularly for hydrogen, but also for oxygen and nitrogen, both chemically important elements. ------------------------------------------------------------------------------------ Observations Description ------------------------ This program aims to acquire high-S/N FUV spectroscopy of nearby 'solar type' (G and K dwarf) stars so the high energy radiation and particle environments can be estimated as inputs to exoplanet atmopshere models. We use COS over STIS as it is the only way to acheive high-S/N obsrvations in weak, but important, FUV tracers Fe XXI 1354 and O IV] 1401 (required to estimate the X-ray and stellar wind conditions). Other essential travers for estimating the complete EUV environment are C II 1335 and Si IV 1394/1403, and when possible C III 1175 and N V 1240 to complete the FUV temperature coverage and enable estimates of the EUV irradiance. These observations need to be coordinated with XMM to be contemporaneous, as specified in the approved Phase I proposal. The HST observing plan is built off the successful MUSCLES Treasury Survey (13650), and acquires targets with a COS ACQ/IMAGE as these stars are all within 50 pc and have high quality Hipparchos or Gaia data available. We observe in G130M lam1291 to cover all of these lines. We restrict observations to FP-POS = 3 and 4 as they are the only two supported modes that access all of these tracers simultaneously. Two targets, kappa1 Cet and epsilon Eri, have stellar LyA profiles that exceed the COS bright limit, so we will observe with segment A only for these targets. We cleared the fields with the APT BOT tool and created ETC runs for all targets/modes during the Phase II preparation. 15825( 12) - 18-Mar-2021 19:59:15 - [ 2] ------------------------------------------------------------------------------------ 15825( 12) - 18-Mar-2021 19:59:15 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 V-V993-TAU EXT-STAR, G V-IV RA=04H27M35.8914S +/- 0.1", J2000 V = V = 7.404 DEC=+15D35'21.09" +/- 0.1" 39.39 Reference Frame: ICRS Extended: NO Comments: This object was generated by the targetselector and retrieved from the SIMBAD database, 2018 Gaia coords.
