New Mass-Loss Measurements from Astrospheric Lyα Absorption
Measurements of stellar mass-loss rates are used to assess how wind strength varies with coronal activity and age for solar-like stars. Mass loss generally increases with activity, but we find
Measured Mass‐Loss Rates of Solar‐like Stars as a Function of Age and Activity
Collisions between the winds of solar-like stars and the local interstellar medium result in a population of hot hydrogen gas surrounding these stars. Absorption from this hot H i can be detected in
What Is the Total Deuterium Abundance in the Local Galactic Disk
Analyses of spectra obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite, together with spectra from the Copernicus and interstellar medium absorption profile spectrograph
Stellar Lyα Emission Lines in the Hubble Space Telescope Archive: Intrinsic Line Fluxes and Absorption from the Heliosphere and Astrospheres*
We search the Hubble Space Telescope (HST) archive for previously unanalyzed observations of stellar H I Lyα emission lines, our primary purpose being to look for new detections of Lyα absorption
The Structure of the Local Interstellar Medium. IV. Dynamics, Morphology, Physical Properties, and Implications of Cloud-Cloud Interactions*
We present an empirical dynamical model of the LISM based on 270 radial velocity measurements for 157 sight lines toward nearby stars. Physical parameter measurements (i.e., temperature, turbulent
Relations among stellar X-ray emission observed from Einstein, stellar rotation and bolometric luminosity
We have determined the correlation between observed stellar X-ray luminosities, bolometric luminosities, and projected rotational velocities v sin / for stars of various spectral types and luminosity
Deuterium and the Local Interstellar Medium: Properties for the Procyon and Capella Lines of Sight
We present Goddard High-Resolution Spectrograph observations of the interstellar H I and D I Lyct lines and the Mg II and Fen resonance lines formed along the lines of sight toward the nearby stars
Complex C: A Low-Metallicity, High-Velocity Cloud Plunging into the Milky Way*
We present evidence that high-velocity cloud (HVC) complex C is a low-metallicity gas cloud that is plunging toward the disk and beginning to interact with the ambient gas that surrounds the Milky
The Far-Ultraviolet Spectrum of TW Hydrae. I. Observations of H2 Fluorescence
We observed the classical T Tauri star TW Hya with the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope (HST) using the E140M grating, from 1150 to 1700 A, with the E230M
Atomic Deuterium/Hydrogen in the Galaxy
An accurate value of the D/H ratio in the local interstellar medium (LISM) and a better understanding of the D/H variations with position in the Galactic disk and halo are vitally important questions
