The NUV transit of XO-3 b
Raven Cilley, Lia Corrales, George W. King +8
Near-UV (NUV) measurements of exoplanet transits offer a means to probe atmospheric escape, cloud formation, and planetary magnetic fields. We examine a 2024 XMM-Newton Optical Mon…
The puzzling story of flare inactive ultra fast rotating M dwarfs -- III. Investigating X-ray Activity
Lauren Doyle, George W. King, Gavin Ramsay +4
According to activity-rotation relations, rapid rotators are expected to show high levels of magnetic activity. However, recent studies with TESS have found Ultra Fast Rotating (UF…
The First Dedicated Survey of Atmospheric Escape from Planets Orbiting F Stars
Morgan Saidel, Shreyas Vissapragada, Heather Knutson +9
Hydrodynamic escape can strip the envelopes of close-in exoplanets, but most observations of atmospheric mass loss to date have been confined to planets orbiting K and M dwarfs. A…
LRG-BEASTS: Detection of sodium and evidence for water absorption in the hot Saturn HAT-P-44b
Alastair B. Claringbold, Peter J. Wheatley, James Kirk +5
We present the low-resolution optical transmission spectrum of the inflated hot Saturn HAT-P-44b. The planet is a close sibling in radius (1.24 ), temperature (11…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
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…
