Fundamental effective temperature measurements for eclipsing binary stars -- VI. Improved methodology and application to the circumbinary planet host star BEBOP-3
P. F. L. Maxted, N. J. Miller, T. A. Baycroft +3
BEBOP-3 is detached eclipsing binary star that shows total eclipses of a faint M~dwarf every 13.2 days by a 9-magnitude F9V star. High precision radial velocity measurem…
MANGOS II: Five new giant planets orbiting low-mass stars
G. Dransfield, M. Timmermans, D. Sebastian +47
Giant planets orbiting low-mass stars on short orbits present a conundrum, as in the most extreme cases their existence cannot be reconciled with current models of core accretion.…
Two warm Earth-sized exoplanets and an Earth-sized candidate in the M5V-M6V binary system TOI-2267
S. Zúñiga-Fernández, F. J. Pozuelos, M. Dévora-Pajares +63
We report two warm Earth-sized exoplanets orbiting the close binary TOI-2267 (M5+M6, separation ~8 au). Data from TESS and ground-based facilities confirm the planets, but we canno…
TOI-2407 b: a warm Neptune in the desert
C. Janó Muñoz, M. J. Hooton, P. P. Pedersen +22
We present the validation of TOI-2407 b, a warm Neptune-sized planet with a radius of 4.26 0.26 R, orbiting an early M-type star with a period of 2.7 days and an equ…
TOI-6508b: A massive transiting brown dwarf orbiting a low-mass star
K. Barkaoui, D. Sebastian, S. Zúñiga-Fernández +44
We report the discovery of a transiting brown dwarf orbiting a low-mass star, TOI-6508b. Today, only ~50 transiting brown dwarfs have been discovered. TOI-6508b was first detected…
TOI-2015b: a sub-Neptune in strong gravitational interaction with an outer non-transiting planet
K. Barkaoui, J. Korth, E. Gaidos +119
TOI-2015 is a known exoplanetary system around an M4 dwarf star, consisting of a transiting sub-Neptune planet in a 3.35-day orbital period, TOI-2015b, accompanied by a non-transit…
