We present near-infrared observations of the low-mass deeply embedded Class 0/I system 2MASS J17112318-2724315 (2M171123) in the B59 molecular cloud. Bright...

Spectroscopic observations of this X-ray nova with the new 6.5-m MMT on Dec. 1 & 4 show that it contains a black hole primary of at least 6 solar masses. Our...

Large fullerenes and fullerene-based molecules have been proposed as carriers of diffuse interstellar bands (DIBs). The recent detection of the most common...

Aims: We have selected the Galactic H ii region M 43, a close-by apparently spherical nebula ionized by a single star (HD 37061, B0.5 V) to investigate several...

We present the results of a high spectral resolution (lambda / Delta lambda = 49 000) study of the circumstellar (CS) gas around the intermediate mass, pre-main...

We present a catalogue of previously unpublished optical and infrared photometry for a sample of 162 emission-line objects and shell stars visible from the...

Aims. We search for brown dwarfs at the Class 0/I evolutionary stage, or proto brown dwarfs. Methods: We present a multi wavelength study, ranging from optical...

Aims: We aim to demonstrate that the Herschel-ATLAS (H-ATLAS) is suitable for a blind and unbiased survey for debris disks by identifying candidate debris disks...
