About

Patrick Dorval is an astronomer specializing in exoplanet detection and stellar astrophysics, with a particular focus on high-precision radial velocity (RV) techniques and the characterization of young stellar systems. His major contributions include the discovery of δ Scuti pulsations in the young hybrid debris disk star HD 156623, a finding that sheds light on the complex interplay between stellar pulsations and circumstellar material. This work, published in 2019, has garnered 12 citations and highlights his skill in leveraging robotic observatory networks like bRing to monitor bright stars for both exoplanetary transits and stellar variability. Dorval also leads the development of ABORAS, a dual-beam polarimetric robotic aperture for the Sun, designed to feed a dedicated Stokes V polarimeter into the HARPS3 spectrograph. This innovative instrument aims to achieve 10 cm/s RV precision by understanding and mitigating solar-induced stellar noise, a critical step toward detecting Earth-like exoplanets. His work bridges observational astronomy and instrumental innovation, making him a rising figure in the quest to disentangle stellar signals from planetary signatures.
