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…
The CARMENES search for exoplanets around M dwarfs -- LP 714-47b (TOI 442.01): Populating the Neptune desert
S. Dreizler, I., J. +134
We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, m_b = 30.8 +/- 1.5 M_earth , R_b = 4.7 +/- 0.3 R_earth ) located in the 'hot Neptune desert'. Confirma…
A multiple planet system of super-Earths orbiting the brightest red dwarf star GJ887
S. V. Jeffers, S. Dreizler, J. R. Barnes +29
The nearest exoplanets to the Sun are our best possibilities for detailed characterization. We report the discovery of a compact multi-planet system of super-Earths orbiting the ne…
TESS discovery of a super-Earth and three sub-Neptunes hosted by the bright, Sun-like star HD 108236
Tansu Daylan, Kartik Pingle, Jasmine Wright +59
We report the discovery and validation of four extrasolar planets hosted by the nearby, bright, Sun-like (G3V) star HD~108236 using data from the Transiting Exoplanet Survey Satell…
An extremely low-density and temperate giant exoplanet
A. Santerne, L. Malavolta, M. R. Kosiarek +68
Transiting extrasolar planets are key objects in the study of the formation, migration, and evolution of planetary systems. In particular, the exploration of the atmospheres of gia…
Frequency of planets orbiting M dwarfs in the Solar neighbourhood
M. Tuomi, H. R. A. Jones, R. P. Butler +14
The most abundant stars in the Galaxy, M dwarfs, are very commonly hosts to diverse systems of low-mass planets. Their abundancy implies that the general occurrence rate of planets…
Planetary system around the nearby M dwarf GJ 357 including a transiting, hot, Earth-sized planet optimal for atmospheric characterization
R. Luque, E. Pallé, D. Kossakowski +73
We report the detection of a transiting Earth-size planet around GJ 357, a nearby M2.5V star, using data from the Transiting Exoplanet Survey Satellite (TESS). GJ 357 b (TOI-562.01…
Detecting Earth-like Biosignatures on Rocky Exoplanets around Nearby Stars with Ground-based Extremely Large Telescopes
Mercedes López-Morales, Thayne Currie, Johanna Teske +21
As we begin to discover rocky planets in the habitable zone of nearby stars with missions like TESS and CHEOPS, we will need quick advancements on instrumentation and observational…
GJ 832c: A super-earth in the habitable zone
R. A. Wittenmyer, Mikko Tuomi, R. P. Butler +17
We report the detection of GJ 832c, a super-Earth orbiting near the inner edge of the habitable zone of GJ 832, an M dwarf previously known to host a Jupiter analog in a nearly-cir…
