NGTS clusters survey - VI: Stellar rotation in seven young open clusters within the PLATO LOPS2 field

Alexander Hughes, Edward Gillen, Matthew Battley +18

We present NGTS measurements of rotation period distributions for FGKM stars in seven young open clusters spanning ~40--700 Myr within PLATO's first long-stare LOPS2 field. We meas…

The TOI-1117 Multi-planetary System: 3 sub-Neptunes, 1 in both the Neptunian Desert and Radius Valley

Isobel S. Lockley, David J. Armstrong, Jorge Fernández Fernández +33

We present the discovery of three sub-Neptune planets around TOI-1117, a Sun-like star with mass , radius , age Gyr and ef…

NGTS-EB-7, an eccentric, long-period, low-mass eclipsing binary

Toby Rodel, Christopher. A. Watson, Solène Ulmer-Moll +35

Despite being the most common types of stars in the Galaxy, the physical properties of late M dwarfs are often poorly constrained. A trend of radius inflation compared to evolution…

TOI-2374 b and TOI-3071 b: two metal-rich sub-Saturns well within the Neptunian desert

Alejandro Hacker, Rodrigo F. Díaz, David J. Armstrong +40

We report the discovery of two transiting planets detected by the Transiting Exoplanet Survey Satellite (TESS), TOI-2374 b and TOI-3071 b, orbiting a K5V and an F8V star, respectiv…

The XUV-driven escape of the planets around TOI-431 & Lupi

George W. King, Lía R. Corrales, Jorge Fernández Fernández +4

One of the leading mechanisms invoked to explain the existence of the radius valley is atmospheric mass loss driven by X-ray and extreme-ultraviolet irradiation, with this process…

The shared evaporation history of three sub-Neptunes spanning the radius-period valley of a Hyades star

Jorge Fernández Fernández, Peter J. Wheatley, George W. King

We model the evaporation histories of the three planets around K2-136, a K-dwarf in the Hyades open cluster with an age of 700 Myr. The star hosts three transiting planets, with ra…

X-ray irradiation of three planets around Hyades star K2-136

Jorge Fernandez Fernandez, Peter J. Wheatley

We study the X-ray irradiation and likely photoevaporation of the three planets around the star K2-136. These are the Earth-sized K2-136 b, the mini-Neptune K2-136 c, and the super…
