Design of an atmospheric dispersion corrector and double scrambler for improved fiber coupling and illumination uniformity for the HET HRS
Devika K Divakar, Joseph Strubhar, Andrew Pinckney +1
The Hobby--Eberly Telescope High Resolution Spectrograph (HET--HRS) is undergoing a major instrument upgrade to improve its performance over the 360--1000 nm wavelength range. As p…
Optomechanical design of an ADC and image rotator for the HJST Coudé Spectrograph at McDonald Observatory
Devika K Divakar, Phillip MacQueen, Andrew Pinckney +1
High-resolution spectroscopic observations require stable slit illumination and mitigation of atmospheric refraction effects that degrade throughput and spectral fidelity. We prese…
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…
