ESCAPE: a small explorer mission to study the stellar drivers of exoplanet evolution

Allison Youngblood, Kevin France, Brian Fleming +37

The long-term stability of exoplanetary atmospheres depends critically on the extreme-ultraviolet (EUV) photon and high-energy particle fluxes from the host star, which are poorly…

The Chandra-Gaia Catalog of Counterparts: Resolving ambiguous Gaia matches to X-ray sources in the Chandra Source Catalog using Machine Learning

V. Samuel Pérez-Díaz, Vinay L. Kashyap, Joshua D. Ingram +6

We present a framework to cross-match sources from the Chandra Source Catalog (CSC v2.1) with optical sources from Gaia Data Release 3. Unlike purely spatial approaches, we use sou…

Breakthroughs in Cool Star Physics with the Line Emission Mapper X-ray Probe

Jeremy J. Drake, Julián Alvarado Gomez, Costanza Argiroffi +10

We outline some of the highlights of the scientific case for the advancement of stellar high energy physics using the Line Emission Mapper X-ray Probe ({\it LEM}). The key to advan…

A Possible Third Body in the X-Ray System GRS 1747-312 and Models with Higher-Order Multiplicity

Caleb Painter, Rosanne Di Stefano, Vinay L. Kashyap +7

GRS 1747-312 is a bright Low-Mass X-ray Binary in the globular cluster Terzan 6, located at a distance of 9.5 kpc from the Earth. It exhibits regular outbursts approximately every…

Estimating Ejecta Mass Ratios in Kepler's SNR: Global X-Ray Spectral Analysis Including Suzaku Systematics and Emitting Volume Uncertainties

Tyler Holland-Ashford, Patrick Slane, Laura A. Lopez +2

The exact origins of many Type Ia supernovae$\unicode{x2013}$progenitor scenarios and explosive mechanisms$\unicode{x2013}$remain uncertain. In this work, we analyze the global Suz…

Classification of Chandra X-ray Sources in Cygnus OB2

Vinay L. Kashyap, Mario G. Guarcello, Nicholas J. Wright +11

We have devised a predominantly Naive Bayes method to classify the optical/IR matches to X-ray sources detected by Chandra in the Cygnus OB2 association into foreground, member, an…
