Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903

Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173

Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…

History and Habitability of the LP 890-9 Planetary System

Rory Barnes, Laura N. R. do Amaral, Jessica Birky +42

We present numerous aspects of the evolution of the LP 890-9 (SPECULOOS-2/TOI-4306) planetary system, focusing on the likelihood that planet c can support life. We find that the ho…

Optically Quiet, But FUV Loud: Results from comparing the far-ultraviolet predictions of flare models with TESS and HST

James A. G. Jackman, Evgenya L. Shkolnik, R. O. Parke Loyd +1

The far-ultraviolet (FUV) flare activity of low-mass stars has become a focus in our understanding of the exoplanet atmospheres and how they evolve. However, direct detection of FU…

A Dragon's Flame of Many Colours: Multi-wavelength Observations of Flares from the Active M Binary CR Draconis

James A. G. Jackman, Evgenya L. Shkolnik, R. O. Parke Loyd +9

We present the results of a multi-wavelength Pro-Am campaign to study the behaviour of flares from the active M1.5V star binary CR Draconis. CR Dra was observed with TESS 20-s phot…

NGTS-28Ab: A short period transiting brown dwarf

Beth A. Henderson, Sarah L. Casewell, Michael R. Goad +43

We report the discovery of a brown dwarf orbiting a M1 host star. We first identified the brown dwarf within the Next Generation Transit Survey data, with supporting observations f…

Statistical Signatures of Nanoflare Activity. III. Evidence of Enhanced Nanoflaring Rates in Fully Convective stars as Observed by the NGTS

S. D. T. Grant, D. B. Jess, C. J. Dillon +11

Previous examinations of fully-convective M-dwarf stars have highlighted enhanced rates of nanoflare activity on these distant stellar sources. However, the specific role the conve…
