The EBLM Project V. Physical properties of ten fully convective, very-low-mass stars
Alexander von Boetticher, Amaury H. M. J. Triaud, Didier Queloz +28
Measurements of the physical properties of stars at the lower end of the main sequence are scarce. In this context we report masses, radii and surface gravities of ten very-low-mas…
High-Precision Photometry with a scientific CMOS Camera: I Lab Testing of the Marana camera
Ioannis Apergis, Daniel Bayliss, Leonidas Asimakoulas +6
Scientific CMOS cameras are becoming increasingly prevalent in modern observational astronomy. We assess the ability of CMOS image sensors technology to perform high-precision phot…
TESS Duotransit Candidates from the Southern Ecliptic Hemisphere
Faith Hawthorn, Sam Gill, Daniel Bayliss +20
Discovering transiting exoplanets with long orbital periods allows us to study warm and cool planetary systems with temperatures similar to the planets in our own Solar system. The…
High-Precision Photometry with a scientific CMOS Camera: II On-Sky Testing of the Marana camera at the NGTS facility
Ioannis Apergis, Daniel Bayliss, Paul Chote +24
Modern scientific CMOS cameras offer very fast readout speeds and low read noise. In this study, we evaluate the performance of the Andor Marana CMOS camera through on-sky testing…
The EBLM project III. A Saturn-size low-mass star at the hydrogen-burning limit
Alexander von Boetticher, Amaury H. M. J. Triaud, Didier Queloz +19
We report the discovery of an eclipsing binary system with mass-ratio q 0.07. After identifying a periodic photometric signal received by WASP, we obtained CORALIE spectrosc…
Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit
Nolan Grieves, François Bouchy, Monika Lendl +52
We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exopla…
The TESS-Keck Survey II: An Ultra-Short Period Rocky Planet and its Siblings Transiting the Galactic Thick-Disk Star TOI-561
Lauren M. Weiss, Fei Dai, Daniel Huber +61
We report the discovery of TOI-561, a multi-planet system in the galactic thick disk that contains a rocky, ultra-short period planet (USP). This bright () star hosts three…
Revised Temperatures For Two Benchmark M-dwarfs -- Outliers No More
David V. Martin, Tayt Armitage, Alison Duck +7
Well-characterised M-dwarfs are rare, particularly with respect to effective temperature. In this letter we re-analyse two benchmark M-dwarfs in eclipsing binaries from Kepler/K2:…
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…
