The Featherweight Giant: Unraveling the Atmosphere of a 17 Myr Planet with JWST
Pa Chia Thao, Andrew W. Mann, Adina D. Feinstein +29
The characterization of young planets (< 300 Myr) is pivotal for understanding planet formation and evolution. We present the 3-5m transmission spectrum of the 17 Myr, Jupiter-s…
A Model of the C IV 1548, 1550 Doublet Line in T Tauri Stars
Thanawuth Thanathibodee, Connor Robinson, Nuria Calvet +7
The C IV doublet in the UV has long been associated with accretion in T Tauri stars. However, it is still unclear where and how the lines are formed. Here, we present a new C IV li…
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…
The fastest components in stellar jets
Hans Moritz Günther, Catherine Espaillat, Kevin France +8
Young stars accrete mass from a circumstellar disk, but at the same time disk and star eject outflows and jets. These outflows have an onion-like structure where the innermost and…
The MUSCLES Treasury Survey II: Intrinsic Lyman Alpha and Extreme Ultraviolet Spectra of K and M Dwarfs with Exoplanets
Allison Youngblood, Kevin France, R. O. Parke Loyd +9
The ultraviolet (UV) spectral energy distributions of low-mass (K- and M-type) stars play a critical role in the heating and chemistry of exoplanet atmospheres, but are not observa…
The MUSCLES Treasury Survey I: Motivation and Overview
Kevin France, R. O. Parke Loyd, Allison Youngblood +18
Ground- and space-based planet searches employing radial velocity techniques and transit photometry have detected thousands of planet-hosting stars in the Milky Way. The chemistry…
