GJ 367b: A dense ultra-short period sub-Earth planet transiting a nearby red dwarf star
Kristine W. F. Lam, Szilárd Csizmadia, Nicola Astudillo-Defru +75
Ultra-short-period (USP) exoplanets have orbital periods shorter than one day. Precise masses and radii of USPs could provide constraints on their unknown formation and evolution p…
K2-99 revisited: a non-inflated warm Jupiter, and a temperate giant planet on a 522-d orbit around a subgiant
A. M. S. Smith, S. N. Breton, Sz. Csizmadia +29
We report new photometric and spectroscopic observations of the K2-99 planetary system. Asteroseismic analysis of the short-cadence light curve from K2's Campaign 17 allows us to r…
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…
TOI-2285b: A 1.7 Earth-radius Planet Near the Habitable Zone around a Nearby M Dwarf
Akihiko Fukui, Tadahiro Kimura, Teruyuki Hirano +60
We report the discovery of TOI-2285b, a sub-Neptune-sized planet transiting a nearby (42 pc) M dwarf with a period of 27.3 days. We identified the transit signal from the Transitin…
37 New Validated Planets in Overlapping K2 Campaigns
J. P. de Leon, J. Livingston, M. Endl +24
We analysed 68 candidate planetary systems first identified during Campaigns 5 and 6 (C5 and C6) of the NASA \textit{K2} mission. We set out to validate these systems by using a su…
The K2-OjOS Project: New and revisited planets and candidates in K2 campaigns 5, 16, & 18
A. Castro-González, E. Díez Alonso, J. Menéndez Blanco +28
We present the first results of K2-OjOS, a collaborative project between professional and amateur astronomers primarily aimed to detect, characterize, and validate new extrasolar p…
TOI-1749: an M dwarf with a Trio of Planets including a Near-Resonant Pair
A. Fukui, J. Korth, J. H. Livingston +65
We report the discovery of one super-Earth- (TOI-1749b) and two sub-Neptune-sized planets (TOI-1749c and TOI-1749d) transiting an early M dwarf at a distance of 100~pc, which were…
TOI-674b: an oasis in the desert of exo-Neptunes transiting a nearby M dwarf
F. Murgas, N. Astudillo-Defru, X. Bonfils +59
We use TESS, Spitzer, ground-based light curves and HARPS spectrograph radial velocity measurements to establish the physical properties of the transiting exoplanet candidate TOI-6…
TOI-220 : a warm sub-Neptune discovered by TESS
S. Hoyer, D. Gandolfi, D. J. Armstrong +77
In this paper we report the discovery of TOI-220 , a new sub-Neptune detected by the Transiting Exoplanet Survey Satellite (TESS) and confirmed by radial velocity follow-up obse…
Hot planets around cool stars -- two short-period mini-Neptunes transiting the late K-dwarf TOI-1260
I. Y. Georgieva, C. M. Persson, O. Barragán +56
We present the discovery and characterization of two sub-Neptunes in close orbits, as well as a tentative outer planet of a similar size, orbiting TOI-1260 - a low metallicity K6V…
Precise transit and radial-velocity characterization of a resonant pair: a warm Jupiter TOI-216c and eccentric warm Neptune TOI-216b
Rebekah I. Dawson, Chelsea X. Huang, Rafael Brahm +53
TOI-216 hosts a pair of warm, large exoplanets discovered by the TESS Mission. These planets were found to be in or near the 2:1 resonance, and both of them exhibit transit timing…
Large Interferometer For Exoplanets (LIFE): I. Improved exoplanet detection yield estimates for a large mid-infrared space-interferometer mission
S. P. Quanz, M. Ottiger, E. Fontanet +68
One of the long-term goals of exoplanet science is the atmospheric characterization of dozens of small exoplanets in order to understand their diversity and search for habitable wo…
Masses and compositions of three small planets orbiting the nearby M dwarf L231-32 (TOI-270) and the M dwarf radius valley
Vincent Van Eylen, N. Astudillo-Defru, X. Bonfils +69
We report on precise Doppler measurements of L231-32 (TOI-270), a nearby M dwarf ( pc, M, R), which hosts three transiting p…
