Official URL: https://academic.oup.com/mnras/article/519/4/5637/6917158 AbstractWe report the discovery and confirmation of the planetary system TOI-1288. This late G dwarf harbours two planets: TOI-1288 b and TOI-1288 c. We combine TESS space-borne and ground-based transit photometry with HARPS-N and HIRES high-precision Doppler measurements, which we use to constrain the masses of both planets in the system and the radius of planet b. TOI-1288 b has a period of 2.699835 +0.000004 -0.000003 d, a radius of 5.24 ± 0.09 R_earth, and a mass of 42 ± 3 M_earth, making this planet a hot transiting super-Neptune situated right in the Neptunian desert. This desert refers to a paucity of Neptune-sized planets on short period orbits. Our 2.4-yr-long Doppler monitoring of TOI-1288 revealed the presence of a Saturn-mass planet on a moderately eccentric orbit (0.13 +0.07 -0.09) with a minimum mass of 84 ± 7 M_earth and a period of 443 +11 -13 d. The five sectors worth of TESS data do not cover our expected mid-transit time for TOI-1288 c, and we do not detect a transit for this planet in these sectors. | Item URL in elib: | https://elib.dlr.de/195652/ |
