An Ultra-Short Period Super-Earth and a Sub-Neptune Orbiting the K dwarf TOI-4311

Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrew Collier Cameron +95

We report the discovery and characterisation of the multi-planetary system around TOI-4311, a K dwarf kinematically between the Galactic thick disk and Hercules stream. TOI-4311 ho…

Resolved Dust Emission and CO Isotopologues in Giant Molecular Clouds of the Andromeda Galaxy

Chloe Bosomworth, Jan Forbrich, Charles J. Lada +1

Dust emission at submillimeter wavelengths can be used to reliably trace the basic properties of molecular clouds. Early results from a recent Submillimeter Array (SMA) survey of t…

A Disintegrating Rocky Planet with Prominent Comet-like Tails Around a Bright Star

Marc Hon, Saul Rappaport, Avi Shporer +21

We report the discovery of BD+054868Ab, a transiting exoplanet orbiting a bright () K-dwarf (TIC 466376085) with a period of 1.27 days. Observations from NASA's Tr…

Polarized Dust Emission in Arp220: Magnetic Fields in the Core of an Ultraluminous Infrared Galaxy

David L Clements, Qizhou Zhang, K. Pattle +3

Arp 220 is the prototypical Ultraluminous Infrared Galaxy (ULIRG), and one of the brightest objects in the extragalactic far-infrared sky. It is the result of a merger between two…

CO isotopologue-derived molecular gas conditions and CO-to-H conversion factors in M51

Jakob den Brok, María J. Jiménez-Donaire, Adam Leroy +24

Over the past decade, several millimeter interferometer programs have mapped the nearby star-forming galaxy M51 at a spatial resolution of pc. This study combines observ…
