Demise of Kreutz Sungrazing Comet C/2024 S1 (ATLAS) by David Jewitt, Jane Luu, Jing Li

“…We present observations from 0.9 to 0.4 au using the Nordic Optical Telescope showing that (1) nucleus disintegration was ongoing already at 0.7 au pre-perihelion, (2) the activity varied unpredictably with distance, and (3) the nucleus radius was  <600 m (red geometric albedo 0.04 assumed). …”

Ultraviolet Photometry and Habitable Zones of over 2700 Planet-hosting Stars by Xue Li, Song Wang, Henggeng Han, Jifeng Liu

“…In this paper, we conducted a detailed analysis of the UV photometry of over 2700 host stars with confirmed planets, using observational data from the Galaxy Evolution Explorer and Swift Ultraviolet/Optical Telescope missions. We performed aperture photometry on single-exposure images and provided photometric catalogs that can be used to explore a wide range of scientific questions, such as stellar UV activity and planet habitability. …”
