The CARMENES search for exoplanets around M dwarfs. Variability on long timescales as seen in chromospheric indicators

B. Fuhrmeister, S. Czesla, V. Perdelwitz +19

It is clearly established that the Sun has an 11-year cycle that is caused by its internal magnetic field. This cycle is also observed in a sample of M dwarfs. In the framework of…

Espresso observations of HE 0107 $-$ 5240 and other CEMP-no stars with $[Fe/H] \leq - 4.5$

D. Aguado, P. Molaro, E. Caffau +22

HE 0107 $-$ 5240 is a hyper metal-poor star with $[Fe/H] = - 5.39$ . We performed high-res observations with the ESPRESSO spectrograph at the VLT to constrain the kinematical propert…

Physical properties and trigonometric distance of the peculiar dwarf WISE J181005.5 $-$ 101002.3

N. Lodieu, M. R. Zapatero Osorio, E. L. Martin +2

Our goal is to characterise the physical properties of the metal-poor brown dwarf population. In particular, we focus on the recently discovered peculiar dwarf WISE J1810055 $-$ 1010…
