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.…

TOI-757 b: an eccentric transiting mini-Neptune on a 17.5-d orbit

A. Alqasim, N. Grieves, N. M. Rosário +129

We report the spectroscopic confirmation and fundamental properties of TOI-757 b, a mini-Neptune on a 17.5-day orbit transiting a bright star ( mag) discovered by the TESS…

NGTS-30 b/TOI-4862 b: An 1 Gyr old 98-day transiting warm Jupiter

M. P. Battley, K. A. Collins, S. Ulmer-Moll +63

Long-period transiting exoplanets bridge the gap between the bulk of transit- and Doppler-based exoplanet discoveries, providing key insights into the formation and evolution of pl…

TOI-1130: A photodynamical analysis of a hot Jupiter in resonance with an inner low-mass planet

J. Korth, D. Gandolfi, J. Šubjak +59

The TOI-1130 is a known planetary system around a K-dwarf consisting of a gas giant planet, TOI-1130 c, on an 8.4-day orbit, accompanied by an inner Neptune-sized planet, TOI-1130…

TOI-969: a late-K dwarf with a hot mini-Neptune in the desert and an eccentric cold Jupiter

J. Lillo-Box, D. Gandolfi, D. J. Armstrong +60

The current architecture of a given multi-planetary system is a key fingerprint of its past formation and dynamical evolution history. Long-term follow-up observations are key to c…

The young HD 73583 (TOI-560) planetary system: Two 10-M mini-Neptunes transiting a 500-Myr-old, bright, and active K dwarf

O. Barragán, D. J. Armstrong, D. Gandolfi +103

We present the discovery and characterisation of two transiting planets observed by \textit{TESS} in the light curves of the young and bright (V=9.67) star HD73583 (TOI-560). We pe…
