We present infrared spectral energy distributions of 23 late-type T and Y dwarfs obtained
with the James Webb Space Telescope. The spectral energy distributions consist of …

Precise mass constraints are vital for the characterisation of brown dwarfs and exoplanets.
Here we present how the combination of data obtained by Gaia and GRAVITY can help …

The stellar initial mass function (IMF) characterizes the mass distribution of newly formed
stars in various cosmic environments, serving as a fundamental assumption in astrophysical …

Abstract Brown Dwarfs (BDs) are crucial objects in our understanding of both star and planet
formation, as well as in our understanding of what mechanisms shape the lower end of the …

This review highlights the role of the Gaia space mission in transforming white dwarf
research. These stellar remnants constitute 5%–7% of the local stellar population in volume …

The discovery and characterization of free-floating planetary-mass objects (FFPMOs) is
fundamental to our understanding of star and planet formation. Here we report results from …

We explain the large variety of star formation laws in terms of one single, simple law that can
be inferred from the definition of the star formation rate and basic algebra. The resulting …

Aims. Our goals are to characterise the kinematic properties and to identify young and old
stars among the M dwarfs of the CARMENES input catalogue. Methods. We compiled the …

We present VIRAC2, a catalogue of positions, proper motions, parallaxes and Z, Y, J, H, and
near-infrared photometric time series of 545 346 537 unique stars. The catalogue is based …

We present the discovery of 13 new widely separated T dwarf companions to M dwarf
primaries, identified using Wide-field Infrared Survey Explorer/NEOWISE data by the …
