Revisiting Radial Velocity Measurements of the K2-18 System with the Line-by-Line Framework
Michael Radica, Étienne Artigau, David Lafrenière +9
The cross-correlation function and template matching techniques have dominated the world of precision radial velocities for many years. Recently, a new technique, named line-by-lin…
TESS discovery of a sub-Neptune orbiting a mid-M dwarf TOI-2136
Tianjun Gan, Abderahmane Soubkiou, Sharon X. Wang +60
We present the discovery of TOI-2136b, a sub-Neptune planet transiting every 7.85 days a nearby M4.5V-type star, identified through photometric measurements from the TESS mission.…
Variability of Brown Dwarfs
Étienne Artigau
Brown dwarfs constitute a missing link between low-mass stars and giant planets. Their atmospheres display chemical species typical of planets, and one could wonder whether they al…
PSYM-WIDE: a survey for large-separation planetary-mass companions to late spectral type members of young moving groups
Marie-Eve Naud, Étienne Artigau, René Doyon +5
We present the results of a direct-imaging survey for very large separation (100 au), companions around 95 nearby young K5-L5 stars and brown dwarfs. They are high-likelihood ca…
