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…
High-Resolution Echelle Spectroscopy for Solar System Planets: A Planet-as-Point-Source Analogy
Parvathy Menon, Sivarani T, Sriram S +4
Transmission spectroscopy has proven to be an effective technique for characterizing exoplanet atmospheres. However, transmission spectroscopy requires planetary transits, which oc…
Atmospheric Dispersion Measurement at Hanle Site
Manjunath Bestha, Sivarani Thirupathi, Athira Unni +2
Atmospheric dispersion introduces wavelength-dependent effects that significantly impact ground-based observations, particularly in slit- and fibre-fed spectroscopic studies. These…
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…
Design overview of the fiber feed for the Hobby-Eberly telescope's HRS
Devika K Divakar, Phillip MacQueen, Joseph Strubhar
We present the redesign of the fiber feed for the High Resolution Spectrograph (HRS) at the Hobby Eberly Telescope (HET). The upgrade incorporates a static atmospheric dispersion c…
An Initial Assessment of the Hanle Echelle Spectrograph for Exoplanet Atmosphere Studies
Manjunath Bestha, Athira Unni, T. Sivarani +6
Transmission spectroscopy is an effective technique for probing exoplanetary atmospheres. While most observations have relied on space facilities such as HST and JWST, ground-based…
