Abstract In this paper, we present a homogeneous analysis of close-in Neptune planets. To do this, compile sample TESS-observed planets using ranking criterion which takes into account the planet’s period, radius, and visual magnitude its host star. We use archival new HARPS data to ensure every target in has precise radial velocities. This yields total 64 targets, 46 are confirmed 18 show no significant velocity signal. explore mass-radius distribution, planetary density, stellar...
ABSTRACT We report the discovery of two transiting planets detected by Transiting Exoplanet Survey Satellite (TESS), TOI-2374 b and TOI-3071 b, orbiting a K5V an F8V star, respectively, with periods 4.31 1.27 d, respectively. confirm characterize these variety ground-based follow-up observations, including photometry, precise radial velocity monitoring high-resolution imaging. The planetary orbital parameters were derived from joint analysis velocities photometric data. found that have...
