A 43 day transiting Neptune and two 25 day Saturns from TESS, NGTS and ASTEP

Alicia Kendall, Solène Ulmer-Moll, Samuel Gill +53

Beyond orbital periods of 10 days, there is a dearth of known transiting gas giants. On longer orbits, planets are less affected by their host star, and become ideal probes of plan…

TOI-7166 b: A Habitable Zone mini-Neptune planet around a nearby low-mass star

Khalid Barkaoui, Francisco J. Pozuelos, Benjamin V. Rackham +41

We present the discovery and validation of TOI-7166b, a 2.01+/-0.05R_Earth planet orbiting a nearby low-mass star. We validated the planet by combining TESS and multi-color high-pr…

Multicolour Validation of Two Temperate Mini-Neptunes Around M-dwarf Habitable Zones

Chengzi Jiang, Aleksandra Selezneva, Hannu Parviainen +17

For small planets orbiting within the habitable zones of their host stars, multicolour validation via photometric transit observations offers an efficient alternative to prioritize…

Migration and Evolution of giant ExoPlanets (MEEP) II: Super-Jupiters and Lithium-rich Host Stars

Jack Schulte, Joseph E. Rodriguez, David W. Latham +30

Although hot Jupiters were the first exoplanets discovered orbiting main sequence stars, the dominant mechanisms through which they form and evolve are not known. To address the qu…

Validation of TESS Planet Candidates with Multi-Color Transit Photometry and TRICERATOPS+

Jonathan Gomez Barrientos, Michael Greklek-McKeon, Heather A. Knutson +33

We present an upgraded version of TRICERATOPS, a software package designed to calculate false positive probabilities for planet candidates identified by the Transiting Exoplanet Su…

The Probable Direct-Imaging Detection of the Stellar Companion to Betelgeuse

Steve B. Howell, David R. Ciardi, Catherine A. Clark +3

Betelgeuse -- the closest M-supergiant to the Sun -- has recently been predicted to host a lower-mass stellar companion that orbits the primary with a period of years. The…

A New Brown Dwarf Orbiting an M star and An Investigation on the Eccentricity Distribution of Transiting Long-Period Brown Dwarfs

Tianjun Gan, Charles Cadieux, Shigeru Ida +32

The orbital eccentricities of brown dwarfs encode valuable information of their formation and evolution history, providing insights into whether they resemble giant planets or stel…

TOI-1846b: A super-Earth in the radius valley orbiting a nearby M dwarf

Abderahmane Soubkiou, Khalid Barkaoui, Zouhair Benkhaldoun +42

We present the discovery and validation of a super-Earth planet orbiting the M dwarf star TOI-1846 (TIC 198385543). The host star(Kmag = 9.6)is located 47 pc away and has a radius…

A transiting giant planet in orbit around a 0.2-solar-mass host star

Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56

Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…

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…

Nearly a Decade of Groundbreaking Speckle Interferometry at the International Gemini Observatory

Steve B. Howell, Clara E. Martínez-Vázquez, Elise Furlan +8

Since its inception, speckle interferometry has revolutionized high-resolution astronomical imaging, overcoming atmospheric challenges to achieve the diffraction limits of telescop…

DW Cnc: a micronova with a negative superhump and a flickering spin

M. Veresvarska, S. Scaringi, C. Littlefield +15

Magnetic accreting white dwarfs in cataclysmic variables have been known to show bursts driven by different physical mechanisms; however, the burst occurrence is much rarer than in…

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…

A 16 Myr super-Neptune in Upper-Centaurus Lupus and a preliminary survey of transiting planets in Sco-Cen with TESS

Sydney Vach, George Zhou, Andrew W. Mann +25

Measuring the properties of planets younger than about 50 Myr helps to test different planetary formation and evolution models. NASA's Transiting Exoplanet Survey Satellite (TESS)…

A Pair of Dynamically Interacting Sub-Neptunes Around TOI-6054

Maxwell A. Kroft, Thomas G. Beatty, Ian J. M. Crossfield +31

We confirm the planetary nature of a pair of transiting sub-Neptune exoplanets orbiting the bright F-type sub-giant star TOI-6054 (, ) as a part of the OrCAS radia…
