Giant Tidal Tails of Helium Escaping the Hot Jupiter HAT-P-32 b
Zhoujian Zhang, Caroline V. Morley, Michael Gully-Santiago +14
Capturing planets in the act of losing their atmospheres provides rare opportunities to probe their evolution history. Such analysis has been enabled by observations of the helium…
Post-outburst evolution of bonafide FUor V2493 Cyg: A Spectro-photometric monitoring
Arpan Ghosh, Saurabh Sharma, Joe P. Ninan +11
We present here the results of eight years of our near-simultaneous optical/near-infrared spectro-photometric monitoring of bonafide FUor candidate `V2493 Cyg' starting from 2013 S…
Non-detection of Helium in the Hot Jupiter WASP-48b
Katherine A. Bennett, Seth Redfield, Antonija Oklopčić +3
Hot Jupiters orbiting extremely close to their host star may experience atmospheric escape due to the large amounts of high-energy radiation they receive. Understanding the conditi…
TOI-5375 B: A Very Low Mass Star at the Hydrogen-Burning Limit Orbiting an Early M-type Star
Mika Lambert, Chad F. Bender, Shubham Kanodia +16
The TESS mission detected a companion orbiting TIC 71268730, categorized it as a planet candidate, and designated the system TOI-5375. Our follow-up analysis using radial velocity…
An extreme test case for planet formation: a close-in Neptune orbiting an ultracool star
Gudmundur Stefansson, Suvrath Mahadevan, Yamila Miguel +27
In current theories of planet formation, close-orbiting planets as massive as Neptune are expected to be very rare around low-mass stars. We report the discovery of a Neptune-mass…
Spectroscopy of 9 eruptive young variables using TANSPEC
Arpan Ghosh, Saurabh Sharma, Joe P. Ninan +8
In recent times, 3.6m Devasthal Optical Telescope (DOT) has installed an optical to near infra-red spectrograph, TANSPEC, which provides spectral coverage from 0.55-2.5 microns. Us…
