PyIRD: A Python-Based Data Reduction Pipeline for Subaru/IRD and REACH

Yui Kasagi, Hajime Kawahara, Ziying Gu, T. Hirano et autres

PyIRD is a Python-based pipeline for reducing spectroscopic data obtained with IRD (InfraRed Doppler; Kotani et al. (2018)) and REACH (Rigorous Exoplanetary Atmosphere Characterization with High dispersion coronagraphy; Kotani et al. ( 2020)) on the Subaru Telescope.It is designed to process raw …

K2-399 b is not a planet

J. Lillo-Box, David W. Latham, K. A. Collins, D. J. Armstrong et autres

Context. The transit technique has been very efficient over the past decades in detecting planet-candidate signals. The so-called statistical validation approach has become a popular way of verifying a candidate’s planetary nature. However, the incomplete consideration of false-positive scenarios and data quality …

TOI-757 b: an eccentric transiting mini-Neptune on a 17.5-d orbit

A. Alqasim, N. Grieves, Nelson Augusto Rosário, D. Gandolfi et autres

We report the spectroscopic confirmation and fundamental properties of TOI-757 b, a mini-Neptune on a 17.5-day orbit transiting a bright star ($V = 9.7$ mag) discovered by the TESS mission. We acquired high-precision radial velocity measurements with the HARPS, ESPRESSO, and PFS …

Radial velocity confirmation of a hot super-Neptune discovered by TESS with a warm Saturn-mass companion

E. Knudstrup, D. Gandolfi, G. Nowak, C. M. Persson et autres

We 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 …
