1+ hour, 31+ min ago   (420+ words) Astronomers have spotted a strange interaction between two low-mass objects about 300 light-years from Earth. A small red dwarf star appears to be slowly pulling material from a nearby brown dwarf, creating a long-lasting cosmic feeding process. The system, named ZTF…...

4+ hour, 29+ min ago   (483+ words) On September 28, AstroSat completed eleven years, more than double its intended lifespan. Regrettably, Earth's atmosphere interferes. It absorbs important X-rays and UV rays before they can be studied from the ground. To decode the cosmic mysteries, we needed to place…...

5+ hour, 46+ min ago   (302+ words) The authors of the study, published in the journal Nature Astronomy, said the planet is likely a gas giant orbiting a white dwarf about 270 light-years from Earth. A study of chemical evidence showed that the new planet may have come…...

14+ hour, 28+ min ago   (210+ words) We present a framework for this contamination-dominated regime, fitting all transit epochs jointly with a Gaussian process per epoch for the time-varying stellar contamination and a single atmospheric model shared across epochs. We use pure CO2, H2O, and CH4 models scaled by their…...

13+ hour, 44+ min ago   (182+ words) [astro-ph.GA] Sulfur (S) chemistry in the interstellar medium remains poorly constrained due to the longstanding “missing sulfur” problem, where a significant fraction of cosmic sulfur in molecular clouds remains unidentified. To gain a comprehensive understanding of S chemistry in the…...
