Broad-band spectral properties of absorbed BLAGN from the 2XMMi-SDSS catalogues
We present results for a sample of absorbed Broad-line Active Galactic Nuclei (BLAGN) se-lected from a cross-correlation of the 2XMMi and Sloan Digital Sky...
Brown dwarf candidates from the PennState-Toruń Planet Search with the Hobby-Eberly Telescope .
We present preliminary results of a brown dwarf (BD) detection in a ˜1000 star sample monitored with the ongoing PennState-Toruń Centre for Astronomy Planet...
Brown dwarf census with the Dark Energy Survey year 3 data and the thin disk scale height of early L types
We present a catalogue of 11,745 brown dwarfs with spectral types ranging from L0 to T9, photometrically classified using data from the Dark Energy Survey (DES)...
Brown Dwarfs and Free-Floating Planets in Young Stellar Clusters
Brown dwarfs are substellar objects unable to stably fuse hydrogen in their interior. Since the discovery of the first brown dwarf in an open cluster, namely...
Brown dwarfs and isolated planetary-mass objects in star clusters
Brown dwarfs are objects unable to sustain hydrogen burning in their interiors. Deep surveys and large scale infrared surveys have identified a few hundred...
Brown dwarfs and isolated planets: fifteen years of a discovery
Since the discovery of the first brown dwarfs, Teide 1 and Gl 229B in 1995, several hundreds of substellar objects have been discovered. During these fifteen...
