The EBLM project - XX. Absolute dynamical masses of five low-mass eclipsing binaries, and an evaluation of mass estimation methods

Adam T. Stevenson, Yasmin T. Davis, Daniel Sebastian +8

Eclipsing binaries consisting of a solar-type primary and an M dwarf secondary are key laboratories to study objects at the bottom of the main sequence. Fundamental parameters of s…

The EBLM Project - XIX. The absence of radius inflation in a homogeneous analysis of 66 Northern low-mass eclipsing binaries

Yasmin T. Davis, Amaury H. M. J. Triaud, David V. Martin +30

Precise and accurate measurements of host stars are crucial in the search for Earth-like exoplanets, and M-dwarfs are favourable targets in this quest. Low-mass eclipsing binaries…

CHEOPS observations of V1298 Tau: updated planetary densities and implications on the early evolution of the young system

Hinna Shivkumar, Sérgio Gomes, Jean-Michel Désert +9

The young (10-30 Myr) multi-planet system V1298 Tau presents a unique opportunity to probe the early formation and evolution of young systems. We present new CHEOPS observations of…

An Adolescent and Near-Resonant Planetary System Near the End of Photoevaporation

Mu-Tian Wang, Fei Dai, Hui-Gen Liu +28

Young exoplanets provide vital insights into the early dynamical and atmospheric evolution of planetary systems. Many multi-planet systems younger than 100 Myr exhibit mean-motion…

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…

The EBLM Project XVIII. 3D Obliquities of Five Low-Mass Eclipsing Binaries

Becca Spejcher, David V. Martin, Jake Pandina +17

The formation of tight stellar binaries remains an unsolved problem. There is too much angular momentum in a collapsing and fragmenting protostellar cloud to form a stellar binary…

The EBLM project -- XIII. The absolute dynamical masses of the circumbinary planet host TOI-1338/BEBOP-1

D. Sebastian, A. H. M. J. Triaud, M. Brogi +6

High-contrast eclipsing binaries with low mass M-dwarf secondaries are precise benchmark stars to build empirical mass-radius relationships for fully convective low-mass ($\rm M_{*…

Rotation of planet-harbouring stars

P. F. L. Maxted

The rotation rate of a star has important implications for the detectability, characterisation and stability of any planets that may be orbiting it. This chapter gives a brief over…

Hot subdwarf binaries from the MUCHFUSS project - Analysis of 12 new systems and a study of the short-period binary population

T. Kupfer, S. Geier, U. Heber +6

The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding hot subdwarf stars with massive compact companions like massive white dw…

WASP 1628+10 - an EL CVn-type binary with a very-low-mass stripped-red-giant star and multi-periodic pulsations

P. F. L. Maxted, A. M. Serenelli, T. R. Marsh +3

The star 1SWASP J162842.31+101416.7 (WASP 1628+10) is one of several EL CVn-type stars recently identified using the WASP database, i.e., an eclipsing binary star in which an A-typ…

Irradiated brown dwarfs

S. L. Casewell, M. R. Burleigh, K. A. Lawrie +3

We have observed the post common envelope binary WD0137-349 in the near infrared , and bands and have determined that the photometry varies on the system period (116 min…

Analysis of Two Eclipsing Hot Subdwarf Binaries with a Low Mass Stellar and a Brown Dwarf Companion

V. Schaffenroth, S. Geier, U. Heber +6

The formation of hot subdwarf stars (sdBs), which are core helium-burning stars located on the extended horizontal branch, is still not understood. Many of the known hot subdwarf s…

Orbital periods of twenty two subdwarf B stars

L. Morales-Rueda, P. F. L. Maxted, T. R. Marsh +2

Subdwarf B (sdB) stars are thought to be core helium burning stars with low mass hydrogen envelopes. In recent years it has become clear that many sdB stars lose their hydrogen thr…
