Multi-Mask Least-Squares Deconvolution: Extracting RVs using tailored masks
F. Lienhard, A. Mortier, L. Buchhave +5
To push the radial velocity (RV) exoplanet detection threshold, it is crucial to find more reliable radial velocity extraction methods. The Least-Squares Deconvolution (LSD) techni…
The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities
Lily L. Zhao, Debra A. Fischer, Eric B. Ford +40
Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precisi…
An unusually low density ultra-short period super-Earth and three mini-Neptunes around the old star TOI-561
G. Lacedelli, L. Malavolta, L. Borsato +38
Based on HARPS-N radial velocities (RVs) and TESS photometry, we present a full characterisation of the planetary system orbiting the late G dwarf TOI-561. After the identification…
Global Analysis of the TRAPPIST Ultra-Cool Dwarf Transit Survey
F. Lienhard, D. Queloz, M. Gillon +10
We conducted a global analysis of the TRAPPIST Ultra-Cool Dwarf Transit Survey - a prototype of the SPECULOOS transit search conducted with the TRAPPIST-South robotic telescope in…
TOI-1235 b: a keystone super-Earth for testing radius valley emergence models around early M dwarfs
Ryan Cloutier, Joseph E. Rodriguez, Jonathan Irwin +85
Small planets on close-in orbits tend to exhibit envelope mass fractions of either effectively zero or up to a few percent depending on their size and orbital period. Models of the…
Photometry and Performance of SPECULOOS-South
C. A. Murray, L. Delrez, P. P. Pedersen +16
SPECULOOS-South, an observatory composed of four independent 1m robotic telescopes, located at ESO Paranal, Chile, started scientific operation in January 2019. This Southern Hemis…
