A low-mass sub-Neptune planet transiting the bright active star HD 73344

S. Sulis, I. J. M. Crossfield, A. Santerne +33

Context. Planets with radii of between 2-4 RE closely orbiting solar-type stars are of significant importance for studying the transition from rocky to giant planets. Aims. Our goa…

The EBLM Project XI. Mass, radius and effective temperature measurements for 23 M-dwarf companions to solar-type stars observed with CHEOPS

M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +104

Observations of low-mass stars have frequently shown a disagreement between observed stellar radii and radii predicted by theoretical stellar structure models. This ``radius inflat…

A hidden population of massive white dwarfs: two spotted K+WD binaries

D. M. Rowan, T. Jayasinghe, M. A. Tucker +10

The identification and characterization of massive () white dwarfs is challenging in part due to their low luminosity. Here we present two candidate single-lin…

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…

The "Giraffe": Discovery of a stripped red giant in an interacting binary with a lower giant

T. Jayasinghe, Todd A. Thompson, C. S. Kochanek +13

We report the discovery of a stripped giant + lower giant binary, 2M04123153+6738486 (2M0412), identified during a search for non-interacting compact object-star binaries. 2M0412 i…

The EBLM project -- VIII. First results for M-dwarf mass, radius and effective temperature measurements using CHEOPS light curves

M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +93

The accuracy of theoretical mass, radius and effective temperature values for M-dwarf stars is an active topic of debate. Differences between observed and theoretical values have r…

The EBLM Project VI. The mass and radius of five low-mass stars in F+M binaries discovered by the WASP survey

S. Gill, P. F. L. Maxted, J. A. Evans +27

Some M-dwarfs around F-/G-type stars have been measured to be hotter and larger than predicted by stellar evolution models. Inconsistencies between observations and models need add…

The CORALIE survey for southern extrasolar planets XVIII. Three new massive planets and two low mass brown dwarfs at separation larger than 5 AU

E. L. Rickman, D. Ségransan, M. Marmier +36

Context. Since 1998, a planet-search around main sequence stars within 50~pc in the southern hemisphere has been carried out with the CORALIE spectrograph at La Silla Observatory.…

On the Abundance of Circumbinary Planets

D. J. Armstrong, H. Osborn, D. Brown +5

We present here the first observationally based determination of the rate of occurrence of circumbinary planets. This is derived from the publicly available Kepler data, using an a…

Placing Limits On The Transit Timing Variations Of Circumbinary Exoplanets

D. Armstrong, D. V. Martin, G. Brown +6

We present an efficient analytical method to predict the maximum transit timing variations of a circumbinary exoplanet, given some basic parameters of the host binary. We derive an…
