Precise near-infrared photometry, accounting for precipitable water vapour at SPECULOOS Southern Observatory
Peter P. Pedersen, C. A. Murray, D. Queloz +20
The variability induced by precipitable water vapour (PWV) can heavily affect the accuracy of time-series photometric measurements gathered from the ground, especially in the near-…
SPECULOOS Northern Observatory: searching for red worlds in the northern skies
Artem Y. Burdanov, Julien de Wit, Michaël Gillon +14
SPECULOOS is a ground-based transit survey consisting of six identical 1-m robotic telescopes. The immediate goal of the project is to detect temperate terrestrial planets transiti…
Two temperate super-Earths transiting a nearby late-type M dwarf
L. Delrez, C. A. Murray, F. J. Pozuelos +82
In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M dwarfs provide unique opportunities for characterising their atmospheres, as well as searching fo…
Observation Scheduling and Automatic Data Reduction for the Antarctic telescope, ASTEP+
Georgina Dransfield, Djamel Mekarnia, Amaury H. M. J. Triaud +13
The possibility to observe transiting exoplanets from Dome C in Antarctica provides immense benefits: stable weather conditions, limited atmospheric turbulence, and a night that la…
A Study of Flares in the Ultra-Cool Regime from SPECULOOS-South
C. A. Murray, D. Queloz, M. Gillon +22
We present a study of photometric flares on 154 low-mass () objects observed by the SPECULOOS-South Observatory from 1st June 2018 to 23rd March 2020.…
HST/WFC3 transmission spectroscopy of the cold rocky planet TRAPPIST-1h
L. J. Garcia, S. E. Moran, B. V. Rackham +4
TRAPPIST-1 is a nearby ultra-cool dwarf star transited by seven rocky planets. We observed three transits of its outermost planet, TRAPPIST-1h, using the G141 grism of the Wide Fie…
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.…
TOI-1442 b and TOI-2445 b: two potentially rocky ultra-short period planets around M dwarfs
G. Morello, H. Parviainen, F. Murgas +52
Context. Exoplanets with orbital periods of less than one day are known as ultra-short period (USP) planets. They are relatively rare products of planetary formation and evolution…
