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-…
The EBLM project -- IX. Five fully convective M-dwarfs, precisely measured with CHEOPS and TESS light curves
D. Sebastian, M. I. Swayne, P. F. L. Maxted +85
Eclipsing binaries are important benchmark objects to test and calibrate stellar structure and evolution models. This is especially true for binaries with a fully convective M-dwar…
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…
TOI-836: A super-Earth and mini-Neptune transiting a nearby K-dwarf
Faith Hawthorn, Daniel Bayliss, Thomas G. Wilson +137
We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright ( mag), high proper motion…
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…
The EBLM project X. Benchmark masses, radii and temperatures for two fully convective M-dwarfs using K2
Alison Duck, David V. Martin, Sam Gill +23
M-dwarfs are the most abundant stars in the galaxy and popular targets for exoplanet searches. However, their intrinsic faintness and complex spectra inhibit precise characterisati…
HD 28109 hosts a trio of transiting Neptunian planets including a near-resonant pair, confirmed by ASTEP from Antarctica
Georgina Dransfield, Amaury H. M. J. Triaud, Tristan Guillot +28
We report on the discovery and characterisation of three planets orbiting the F8 star HD~28109, which sits comfortably in \tess's continuous viewing zone. The two outer planets hav…
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.…
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.…
A Possible Alignment Between the Orbits of Planetary Systems and their Visual Binary Companions
Sam Christian, Andrew Vanderburg, Juliette Becker +111
Astronomers do not have a complete picture of the effects of wide-binary companions (semimajor axes greater than 100 AU) on the formation and evolution of exoplanets. We investigat…
A pair of Sub-Neptunes transiting the bright K-dwarf TOI-1064 characterised with CHEOPS
Thomas G. Wilson, Elisa Goffo, Yann Alibert +132
We report the discovery and characterisation of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in TESS photometry. To characterise…
