The small transiting planet population revealed by ESPRESSO with extreme precision radial velocities
M. J. Hobson, B. Lavie, F. Bouchy +35
Small planets are extremely common in the Galaxy, including planets with masses and radii between those of Earth and Neptune. Characterizing these planets' masses requires ultra-pr…
TOI-2322: two transiting rocky planets close to the stellar rotation period and its first harmonic
M. J. Hobson, A. Suárez Mascareño, C. Lovis +42
Context. Active regions on the stellar surface can induce quasi-periodic radial velocity (RV) variations that can mimic planets and mask true planetary signals. These spurious sign…
Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581
João Gomes da Silva, Elisa Delgado-Mena, Nuno C. Santos +145
Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the RV method. The aim of this work is to measure the effect of activity in t…
High-Speed Boulders and the Debris Field in DART Ejecta
Tony L. Farnham, Jessica M. Sunshine, Masatoshi Hirabayashi +44
On 26 September 2022 the Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the moon of the near-Earth asteroid 65803 Didymos, in a full-scale demonstratio…
Acquisition-Independent Deep Learning for Quantitative MRI Parameter Estimation using Neural Controlled Differential Equations
Daan Kuppens, Sebastiano Barbieri, Daisy van den Berg +4
Deep learning has proven to be a suitable alternative to least-squares (LSQ) fitting for parameter estimation in various quantitative MRI (QMRI) models. However, current deep learn…
