An Observational Study of Systematics in Differential Transmission Spectroscopy Using HFOSC on the Himalayan Chandra Telescope
Manjunath Bestha, Athira Unni, T Sivarani +2
Ground-based low-resolution transmission spectroscopy requires photometric precision of a few hundred parts per million, making it sensitive to instrumental and atmospheric systema…

A new broadband atmospheric dispersion corrector for HROS-TMT
Manjunath Bestha, Thirupathi Sivarani, Bachar Wehbe +7
Atmospheric dispersion causes light from celestial objects with different wavelengths to refract at varying angles as it passes through Earth's atmosphere. This effect results in a…

A multi-object approach for studying exoplanet atmospheres using high-resolution spectrographs
Manjunath Bestha, Athira Unni, T. Sivarani +5
Atmospheric characterization of exoplanets has traditionally relied on Low-Resolution Transmission Spectroscopy (LRTS), obtained from both space- and ground-based facilities, as we…
