Giant Outer Transiting Exoplanet Mass (GOTEM) Survey.VII. TOI-6041: a multi-planet system including a warm Neptune exhibiting strong TTVs
N. Heidari, A. Alnajjarine, H. P. Osborn +101
We present the characterization of the TOI-6041 system, a bright () G7-type star hosting at least two planets. The inner planet, TOI-6041b, is a warm Neptune wit…
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…
Mass determination of the three long-period Neptune- and sub-Neptune-sized planets transiting TOI-282
A. Barone, F. Rodler, D. Gandolfi +16
TOI-282 is a bright (V=9.38) F8 main-sequence star known to host three transiting long-period (=22.9 d, =56.0 d, and =84.3 d) small ( 2-4 ) p…
A planetary system with a sub-Neptune planet in the habitable zone of TOI-2093
J. Sanz-Forcada, E. González-Ãlvarez, M. R. Zapatero Osorio +33
Aims. We aim to confirm and measure the mass of the transiting planet candidate around the K5V star TOI-2093, previously announced by the Transiting Exoplanet Survey Satellite (TES…
A four-planet system orbiting the old thick disk star TOI-1203
D. Gandolfi, A. Alnajjarine, L. M. Serrano +120
TOI-1203 is a bright (V=8.6) G3 V star known to host a transiting warm sub-Neptune on a 25.5 d orbit. Here we report on an intensive high-precision radial velocity and photometric…
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…
