    The CARMENES search for exoplanets around M dwarfs. Variability of the He I line at 10 830 Å
    The He I infrared (IR) triplet at 10 830 Å is known as an activity indicator in solar-type stars and has become a primary diagnostic in exoplanetary...

    The CARMENES search for exoplanets around M dwarfs. Variability on long timescales as seen in chromospheric indicators
    It is clearly established that the Sun has an 11-yr cycle that is caused by its internal magnetic field. Such a cycle is also observed in a sample of M dwarfs...

    The CARMENES search for exoplanets around M dwarfs. Wing asymmetries of Hα, Na I D, and He I lines
    Stellar activity is ubiquitously encountered in M dwarfs and often characterised by the Hα line. In the most active M dwarfs, Hα is found in emission, sometimes...

    The CARMENES search for exoplanets around M dwarfs. Wolf 1069 b: Earth-mass planet in the habitable zone of a nearby, very low-mass star
    We present the discovery of an Earth-mass planet (M b sin i = 1.26 ± 0.21 M ⊕) on a 15.6 d orbit of a relatively nearby (d ~ 9.6 pc) and low-mass (0.167 ± 0.011...

    The CARMENES Search for Exoplanets around M Dwarfs: A Low-mass Planet in the Temperate Zone of the Nearby K2-18
    K2-18 is a nearby M2.5 dwarf, located at 34 pc and hosting a transiting planet that was first discovered by the K2 mission and later confirmed with Spitzer...

    The CARMENES search for exoplanets around M dwarfs: Magnesium and silicon abundances of K7–M5.5 stars
    We present the abundances of magnesium (Mg) and silicon (Si) for 314 dwarf stars with spectral types in the interval K7.0–M5.5 (T eff range ≈ 4200–3050 K)...

    The CARMENES search for exoplanets around M dwarfs: The impact of rotation and magnetic fields on the radial velocity jitter in cool stars
    Context. Radial velocity (RV) jitter represents an intrinsic limitation on the precision of Doppler searches for exoplanets that can originate from both...

    The case for AGN feedback in galaxy groups
    The relatively recent insight that energy input from supermassive black holes (BHs) can have a substantial effect on the star formation rates (SFRs) of galaxies...

    The Castalia mission to Main Belt Comet 133P/Elst-Pizarro
    We describe Castalia, a proposed mission to rendezvous with a Main Belt Comet (MBC), 133P/Elst-Pizarro. MBCs are a recently discovered population of apparently...
