A Minute-Cadence Deep Bulge Survey: First Data Release of DREAMS

Hongjing Yang, Weicheng Zang, Francisco Valdes +33

The DECam Rogue Earths and Mars Survey (DREAMS), a NOIRLab survey program, has been conducting a three-year survey covering a 5 deg area in the Galactic bulge (roughly spanning…

Long-term monitoring of WASP-19 b: Signs of apsidal precession and molecular signatures

A. R. Rajkumar, A. Bayo, P. Peng +30

With more than 6000 exoplanets discovered so far, about 12 percent are hot Jupiters. Their large sizes and short orbital periods make them valuable targets for studying planetary f…

Time-Domain Photometry and Activity Evolution of Interstellar Comet 3I/ATLAS with BHTOM

A. Fraser Gillan, Łukasz Wyrzykowski, Przemysław J. Mikołajczyk +69

Time-domain photometric monitoring is essential for characterizing cometary evolution, particularly for rare interstellar objects with limited observing opportunities. We aimed to…

Gaia20fnr: A binary-lens microlensing event with full orbital motion revealed by four space telescopes

M. Wicker, Ł. Wyrzykowski, M. Hundertmark +49

The microlensing event Gaia20fnr is a long-duration, non-caustic-crossing binary-lens event at high Galactic latitude. Triggered by a photometric rise detected by the Gaia space mi…

KMT-2025-BLG-1616Lb: First Microlensing Bound Planet From DREAMS

Hongjing Yang, Weicheng Zang, Yoon-Hyun Ryu +60

We present observations and analysis of the bound planetary microlensing event KMT-2025-BLG-1616. The planetary signal was captured by the Korea Microlensing Telescope Network (KMT…

A search for transit timing variations in the transiting hot Jupiter systems HIP 65, NGTS-6, NGTS-10 and WASP-173

A. W. Griffiths, J. Southworth, L. Alegre +30

Hot Jupiters are Jupiter-mass planets with orbital periods of less than ten days. Their short orbital separations make tidal dissipation within the stellar host especially efficien…
