TOI-220 : a warm sub-Neptune discovered by TESS

S. Hoyer, D. Gandolfi, D. J. Armstrong +77

In this paper we report the discovery of TOI-220 , a new sub-Neptune detected by the Transiting Exoplanet Survey Satellite (TESS) and confirmed by radial velocity follow-up obse…

Masses and compositions of three small planets orbiting the nearby M dwarf L231-32 (TOI-270) and the M dwarf radius valley

Vincent Van Eylen, N. Astudillo-Defru, X. Bonfils +69

We report on precise Doppler measurements of L231-32 (TOI-270), a nearby M dwarf ( pc, M, R), which hosts three transiting p…

The VVV Infrared Variability Catalog (VIVA-I)

C. E. Ferreira Lopes, N. J. G. Cross, M. Catelan +17

Thanks to the VISTA Variables in the Via Lactea (VVV) ESO Public Survey it is now possible to explore a large number of objects in those regions. This paper addresses the variabili…

A hot terrestrial planet orbiting the bright M dwarf L 168-9 unveiled by TESS

N. Astudillo-Defru, R. Cloutier, S. X. Wang +67

We report the detection of a transiting super-Earth-sized planet (R=1.39+-0.09 Rearth) in a 1.4-day orbit around L 168-9 (TOI-134),a bright M1V dwarf (V=11, K=7.1) located at 25.15…

Masses of the Hyades white dwarfs: A gravitational redshift measurement

L. Pasquini, A. F. Pala, H. -G. Ludwig +3

Context. It is possible to accurately measure the masses of the white dwarfs (WDs) in the Hyades cluster using gravitational redshift, because the radial velocity of the stars can…

Multifractal detrended moving average analysis of Kepler stars with surface differential rotation traces

D. B. de Freitas, M. M. F. Nepomuceno, J. G. Cordeiro +2

A multifractal formalism is employed to analyse high-precision time-series data of \textit{Kepler} stars with surface differential rotation traces. The multifractal detrended movin…
