First Resolution of a Main Sequence G-Star Astrosphere Using Chandra

C. M. Lisse, S. J. Wolk, B. Snios +24

We report resolution of a halo of X-ray line emission surrounding the Zero Age Main Sequence (ZAMS) G8.5V star HD 61005 by Chandra ACIS-S. Located only 36.4 pc distant, HD 61005 is…

Toward a 2D H I Map of the Local Interstellar Medium

Allison Youngblood, Kevin France, Tommi Koskinen +9

Obtaining a complete census of gas in the local interstellar medium (<100 pc) is challenging given the limited available tracers of the warm, partially-ionized medium. Medium-to-hi…

Twenty-Five Years of Accretion onto the Classical T Tauri Star TW Hya

Gregory J. Herczeg, Yuguang Chen, Jean-Francois Donati +39

Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time…

Intrinsic Lyman alpha Profiles of High-Velocity G, K, and M Dwarfs

Allison Youngblood, J. Sebastian Pineda, Thomas Ayres +5

Observations of H I Lyman alpha, the brightest UV emission line of late-type stars, are critical for understanding stellar chromospheres and transition regions, modeling photochemi…

The Mega-MUSCLES Spectral Energy Distribution Of TRAPPIST-1

David J. Wilson, Cynthia S. Froning, Girish M. Duvvuri +19

We present a 5A-100um Spectral Energy Distribution (SED) of the ultracool dwarf star TRAPPIST-1, obtained as part of the Mega-MUSCLES Treasury Survey. The SED combines ultraviolet…

Reconstructing the Extreme Ultraviolet Emission of Cool Dwarfs Using Differential Emission Measure Polynomials

Girish M. Duvvuri, J. Sebastian Pineda, Zachory K. Berta-Thompson +16

Characterizing the atmospheres of planets orbiting M dwarfs requires understanding the spectral energy distributions of M dwarfs over planetary lifetimes. Surveys like MUSCLES, HAZ…
