Mass constraints for the K2-223 system planets: An ultra-short-period sub-Earth, a short-period super-Earth, and a tentative long-period giant planet
Dawid Jankowski, Grzegorz Nowak, Gaia Lacedelli +23
We present mass constraints of two short-period Earth-sized planets transiting K2-223 based on high-precision radial velocity measurements from HARPS-N and ESPRESSO, as well as a t…
A gem system with a lava world and a habitable zone sub-Neptune orbiting TOI-1752
A. Peláez-Torres, F. J. Pozuelos, G. Morello +47
The Transiting Exoplanet Survey Satellite (TESS) has delivered a large number of transiting planet candidates around nearby stars by identifying periodic decreases in stellar brigh…
WD 1054-226 revisited: a stable transiting debris system
J. Korth, A. J. Mustill, H. Parviainen +24
A growing number of white dwarfs (WDs) exhibit one or more signs of remnant planetary systems, including transits, infrared excesses, and atmospheric metal pollution. WD 1054-226 s…
Characterization of two new transiting sub-Neptunes and a terrestrial planet around M-dwarf hosts
E. Poultourtzidis, G. Lacedelli, E. Pallé +49
We report the confirmation of three transiting exoplanets orbiting TOI-1243 (LSPM~J0902+7138), TOI-4529 (G~2--21), and TOI-5388 (Wolf~346) that were initially detected by TESS thro…
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…
Searching for Exoplanets Born Outside the Milky Way: VOYAGERS Survey Design
Robert Aloisi, Andrew Vanderburg, Melinda Soares-Furtado +44
Observations over the past few decades have found that planets are common around nearby stars in our Galaxy, but little is known about planets that formed outside the Milky Way. We…
Sibling Sub-Neptunes Around Sibling M Dwarfs: TOI-521 and TOI-912
G. Lacedelli, E. Pallé, R. Luque +47
Sub-Neptunes are absent in the Solar System, yet they are commonly found in our Galaxy. They challenge the internal structure models and prompt investigation on their formation, ev…
Discovery of a transiting hot water-world candidate orbiting Ross 176 with TESS and CARMENES
S. Geraldía-González, J. Orell-Miquel, E. Pallé +30
The case of Ross 176 is a late K-type star that hosts a promising water-world candidate planet. The star has a radius of =0.5690.020 and a mass of …
A transiting rocky super-Earth and a non-transiting sub-Neptune orbiting the M dwarf TOI-771
G. Lacedelli, E. Pallé, Y. T. Davis +24
The origin and evolution of the sub-Neptune population is a highly debated topic in the exoplanet community. With the advent of JWST, atmospheric studies can now put unprecedented…
TOI-2015b: a sub-Neptune in strong gravitational interaction with an outer non-transiting planet
K. Barkaoui, J. Korth, E. Gaidos +119
TOI-2015 is a known exoplanetary system around an M4 dwarf star, consisting of a transiting sub-Neptune planet in a 3.35-day orbital period, TOI-2015b, accompanied by a non-transit…
Validation of up to seven TESS planet candidates through multi-colour transit photometry using MuSCAT2 data
A. Peláez-Torres, E. Esparza-Borges, E. Pallé +62
The TESS mission searches for transiting exoplanets by monitoring the brightness of hundreds of thousands of stars across the entire sky. M-type planet hosts are ideal targets for…
Gliese 12 b: A temperate Earth-sized planet at 12 pc ideal for atmospheric transmission spectroscopy
M. Kuzuhara, A. Fukui, J. H. Livingston +103
Recent discoveries of Earth-sized planets transiting nearby M dwarfs have made it possible to characterize the atmospheres of terrestrial planets via follow-up spectroscopic observ…
The Discovery and Follow-up of Four Transiting Short-period Sub-Neptunes Orbiting M dwarfs
Y. Hori, A. Fukui, T. Hirano +100
Sub-Neptunes with are intermediate in size between rocky planets and Neptune-sized planets. The orbital properties and bulk compositions of transiting sub-Neptunes pr…
TOI-4438 b: a transiting mini-Neptune amenable to atmospheric characterization
E. Goffo, P. Chaturvedi, F. Murgas +47
We report the confirmation and mass determination of a mini-Neptune transiting the M3.5 V star TOI-4438 (G 182-34) every 7.44 days. A transit signal was detected with NASA's TESS s…
Wolf 327b: A new member of the pack of ultra-short-period super-Earths around M dwarfs
F. Murgas, E. Pallé, J. Orell-Miquel +52
Planets with orbital periods shorter than 1 day are rare and have formation histories that are not completely understood. Small () ultra-short-period (…
