ATLAS Photometry of Interstellar Object 3I/ATLAS
John Tonry, Larry Denneau, Miguel Alarcon +7
We present calibrated ATLAS photometry of the interstellar comet 3I/ATLAS (C/2025 N1) from 28 March through 29 Aug 2025, obtained with the five-site, robotic ATLAS network in the c…
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…
Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS
Darryl Z. Seligman, Marco Micheli, Davide Farnocchia +44
We report initial observations aimed at the characterization of a third interstellar object. This object, 3I/ATLAS or C/2025 N1 (ATLAS), was discovered on 2025 July 1 UT and has an…
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 birth of Be star disks I. From localized ejection to circularization
J. Labadie-Bartz, A. C. Carciofi, A. C. Rubio +35
Classical Be stars are well known to eject mass, but the details governing the initial distribution and evolution of this matter into a disk are poorly constrained by observations.…
