Searching for helium escape and a low density atmosphere around the 120 Myr old sub-Neptune HIP94235b using CRIRES+
Ava Morrissey, George Zhou, Chelsea X. Huang +6
Atmospheric mass loss is thought to induce the bimodality in the small planet population as we observe it today. Observationally, active mass loss can be traced by excess absorptio…
Open Source High-Resolution Exoplanet Atmosphere Retrievals with POSEIDON
Ruizhe Wang, Ryan J. MacDonald, Neale P. Gibson +1
High-resolution spectroscopy (R > 25,000) has opened new opportunities to characterize exoplanet atmospheres from the ground. By resolving individual lines in planetary emission an…
Hot Rocks Survey I : A possible shallow eclipse for LHS 1478 b
Prune C. August, Lars A. Buchhave, Hannah Diamond-Lowe +18
M dwarf systems offer an opportunity to study terrestrial exoplanetary atmospheres due to their small size and cool temperatures. However, the extreme conditions imposed by these h…
New perspectives on MASCARA-1b: A combined analysis of pre- and post-eclipse emission data using CRIRES+
Swaetha Ramkumar, Neale P. Gibson, Stevanus K. Nugroho +2
We present high-resolution emission spectroscopy observations of the ultra-hot Jupiter MASCARA-1b with CRIRES+ in the K-band, covering the post-eclipse phases of its orbit. These o…
Assessing methods for telluric removal on atmospheric retrievals of high-resolution optical exoplanetary transmission spectra
Cathal Maguire, Elyar Sedaghati, Neale P. Gibson +2
Recent advancements in ultra-stable ground-based high-resolution spectrographs have propelled ground-based astronomy to the forefront of exoplanet detection and characterisation. R…
