The CARMENES search for exoplanets around M dwarfs: Spectroscopic orbits of nine M-dwarf multiple systems, including two triples, two brown dwarf candidates, and one close M-dwarf-white dwarf binary
D. Baroch, J. C. Morales, I. Ribas +33
M dwarfs are ideal targets for the search of Earth-size planets in the habitable zone using the radial velocity method, attracting the attention of many ongoing surveys. As a by-pr…
Monitoring the radio emission of Proxima Centauri
Miguel Pérez-Torres, José Francisco Gómez, José Luis Ortiz +15
We present results from the most comprehensive radio monitoring campaign towards the closest star to our Sun, Proxima Centauri. We report 1.1 to 3.1 GHz observations with the Austr…
Identification and Mitigation of a Vibrational Telescope Systematic with Application to Spitzer
Ryan C. Challener, Joseph Harrington, James Jenkins +17
We observed Proxima Centauri with the Spitzer Space Telescope InfraRed Array Camera (IRAC) five times in 2016 and 2017 to search for transits of Proxima Centauri b. Following stand…
Stellar activity analysis of Barnard's Star: Very slow rotation and evidence for long-term activity cycle
B. Toledo-Padrón, J. I. González Hernández, C. Rodríguez-López +58
The search for Earth-like planets around late-type stars using ultra-stable spectrographs requires a very precise characterization of the stellar activity and the magnetic cycle of…
High-cadence spectroscopy of M-dwarfs - II. Searching for stellar pulsations with HARPS
Zaira M. Berdiñas, Cristina Rodríguez-López, Pedro J. Amado +5
Stellar oscillations appear all across the Hertzsprung-Russell diagram. Recent theoretical studies support their existence also in the atmospheres of M dwarfs. These studies predic…
High-cadence spectroscopy of M-dwarfs. I. Analysis of systematic effects in HARPS-N line profile measurements on the bright binary GJ 725A+B
Zaira M. Berdiñas, Pedro J. Amado, Guillem Anglada-Escudé +2
Understanding the sources of instrumental systematic noise is a must to improve the design of future spectrographs. In this study, we alternated observations of the well-suited pai…
