Dust production rates in Jupiter-family comets II: Trends and population insights from ATLAS photometry of 116 JFCs

A. Fraser Gillan, Alan Fitzsimmons, Larry Denneau +4

Jupiter-family comets (JFCs) have orbital periods of less than 20 years and therefore undergo more frequent sublimation compared to other comet populations. The JFCs therefore repr…

The Multiband Imaging Survey for High-Alpha PlanetS (MISHAPS) I: Preliminary Constraints on the Occurrence Rate of Hot Jupiters in 47 Tucanae

Alison L. Crisp, Jonas Klüter, Marz L. Newman +14

The first generation of transiting planet searches in globular clusters yielded no detections, and in hindsight, only placed occurrence rate limits slightly higher than the measure…

Disequilibrium Chemistry, Diabatic Thermal Structure, and Clouds in the Atmosphere of COCONUTS-2b

Zhoujian Zhang, Sagnick Mukherjee, Michael C. Liu +12

Located 10.888 pc from Earth, COCONUTS-2b is a planetary-mass companion to a young (150-800 Myr) M3 star, with a wide orbital separation (6471 au) and a low companion-to-host mass…

Analysing the Onset of Cometary Activity by the Jupiter-Family Comet 2023 RN3

Matthew M. Dobson, Megan E. Schwamb, Alan Fitzsimmons +17

We utilize serendipitous observations from the Asteroid Terrestrial-impact Last Alert System (ATLAS) and the Zwicky Transient Facility (ZTF) in addition to targeted follow-up obser…
