TL;DR: The case of CoRoT LRa02_E2_0121, which was initially classified as a Neptune-size transiting-planet candidate on a relatively wide orbit of 36.3 days, was presented in this paper.

TL;DR: ToI-1452b is a transiting super-Earth (R p = 1.67 ± 0.07 R ⊕) in an 11.1 day temperate orbit (T eq = 326 ± 7 K) around the primary member (H = 10.0, T eff = 3185 ± 50 K) of a nearby visual-binary M dwarf as mentioned in this paper .

TL;DR: In this paper, the authors demonstrate an astrocomb generated via soliton formation in an on-chip microphotonic resonator with a resolvable line spacing of 23.7 GHz, providing wavelength calibration on the 10 cm/s radial velocity level on the GIANO-B high resolution near-infrared spectrometer.

Line-by-line Velocity Measurements: an Outlier-resistant Method for Precision Velocimetry
Étienne Artigau,Charles Cadieux,Neil Cook,René Doyon,Thomas Vandal,Jean-François Donati,C. Moutou,Xavier Delfosse,P. Fouqu'e,Eder Martioli,François Bouchy,Jasmine Parsons,Andres Carmona,Xavier Dumusque,Nicola Astudillo-Defru,Xavier Bonfils,Lucille Mignon +16 more
TL;DR: In this paper , a line-by-line (LBL) approach is proposed to handle outlying spectral information in a simple but efficient manner, which is demonstrated on two data sets, one obtained with SPIRou on Barnard's star and the other with the High Accuracy Radial velocity Planet Searcher (HARPS) on Proxima Centauri.
