A Quiet Host in an Active Planet-Forming Disk: Optical Spectroscopy of WISPIT 2
C. Swastik, M. Bestha, L. S. Sonith +11
WISPIT 2 is a young pre-main-sequence star hosting a multi-ringed transition disk and two directly imaged protoplanets, including the accreting WISPIT 2b, making it the closest kno…
Imaging the LkCa 15 system in polarimetry and total intensity without self-subtraction artefacts
C. Swastik, Zahed Wahhaj, Myriam Benisty +7
Studying young protoplanetary disks is essential for understanding planet formation, but traditional angular differential imaging can introduce self-subtraction artefacts that hind…
Venus as an exoplanet analog: extended UV transit signatures and coronal occultations
Tisyagupta Pyne, Belur Ravindra, Ravinder K. Banyal
Stellar activity manifests differently across wavelengths, causing flux variability that can obscure planetary transits. While transit observations are typically performed in the v…
The 10 pc Neighborhood of Habitable Zone Exoplanetary Systems: Threat Assessment from Stellar Encounters & Supernovae
Tisyagupta Pyne, Ravinder K. Banyal, C. Swastik +1
The habitability of a planet is influenced by both its parent star and the properties of its local stellar neighborhood. Potential threats to habitability from the local stellar en…
Low-resolution Transit Spectroscopy of Three Hot Jupiters Using the 2m Himalayan Chandra Telescope
Athira Unni, Thirupathi Sivarani, Jayesh Goyal +3
Here, we present the low-resolution transmission spectroscopy of three giant planets using the Himalayan Faint Object Spectrograph Camera (HFOSC) on the 2m Himalayan Chandra Telesc…
