Optical constraints on the coldest metal-poor population
Jerry Jun-Yan Zhang, Nicolas Lodieu, Eduardo L. MartÃn +10
The coldest metal-poor population made of T and Y dwarfs are archaeological tracers of our Galaxy because they are very old and have kept the pristine material. The optical propert…

CARMENES input catalogue of M dwarfs IX. Multiplicity from close spectroscopic binaries to ultra-wide systems
C. Cifuentes, J. A. Caballero, J. González-Payo +12
Multiplicity studies greatly benefit from focusing on M dwarfs because they are often paired in a variety of configurations with both stellar and substellar objects, including exop…

The CARMENES search for exoplanets around M dwarfs. The impact of rotation and magnetic fields on the radial velocity jitter in cool stars
H. L. Ruh, M. Zechmeister, A. Reiners +19
Radial velocity (RV) jitter represents an intrinsic limitation on the precision of Doppler searches for exoplanets that can originate from both instrumental and astrophysical sourc…
