Machine learning for exoplanet detection in high-contrast spectroscopy [PDF]
Context. The new generation of observatories and instruments (VLT/ERIS, JWST, ELT) motivate the development of robust methods to detect and characterise faint and close-in exoplanets. Molecular mapping and cross-correlation for spectroscopy use molecular

Predicting flux data for exoplanet detection.
, 2023 This paper will focus on utilizing five different methods of machine learning models to properly classify celestial bodies orbiting a star as an exoplanet or a false positive. We will be utilizing a recurrent neural network (RNN), a logistical regression

The Interpolation Constraint in the RV Analysis of M Dwarfs Using Empirical Templates
The Astronomical JournalPrecise radial velocity (pRV) measurements of M dwarfs in the near-infrared rely on empirical templates due to the lack of accurate stellar spectral models in this regime.

A Pair of Dynamically Interacting Sub-Neptunes around TOI-6054
The Astronomical JournalWe confirm the planetary nature of a pair of transiting sub-Neptune exoplanets orbiting the bright F-type subgiant star TOI-6054 ( V = 8.02, K = 6.673) as a part of the OrCAS radial velocity survey using WIYN/NEID observations. We find that TOI-6054b and
