    Two Bright M Dwarfs Hosting Ultra-Short-Period Super-Earths with Earth-like Compositions
    We present observations of two bright M dwarfs (TOI-1634 and TOI-1685: J = 9.5-9.6) hosting ultra-short-period (USP) planets identified by the TESS mission. The...

    Use of high resolution IUE spectra of MG 2 in cool stars to probe the local interstellar medium
    It is shown that, given suitable radial velocity values for the stars and the local interstellar medium (LISM) interstellar absorption can be distinguished from...
