Constraints on the dust extinction law of the Galaxy
This work explores data from a few surveys, most notably the serendipitous catalogue from the NASA SWIFT mission that made use of the NUV/optical camera UVOT...
Cosmic amorphous dust in the interstellar medium as a possible explanation for the Anomalous Microwave Emission
The main emission mechanisms of the interstellar medium (ISM) in the spectral range between the radio and the far infrared are very well characterised and...
Stellar ages are key to several fields of astrophysics such as exoplanet research, galactic-archeology, and of course stellar physics. Obtaining the ages of...
Detection of TiO and Na in the atmosphere of the hot Jupiter HAT-P-65b
We present the low-resolution transmission spectra of the puffy hot Jupiter HAT-P-65b (0.53 MJup, 1.89 RJup, Teq = 1930 K), based on two transits observed using...
Discovery of a massive black hole companion to a B-type star from radial velocity measurements
All stellar-mass black holes have hitherto been identified by X-rays emitted from gas that is accreting onto the black hole from a companion star. These systems...
Discovery of a young forming planet around the nearby star AU Mic
AU Microscopii (AU Mic) is the second closest pre-main-sequence star, at a distance of 9.79 parsecs and with an age of 22 million years . AU Mic possesses a...
Discovery of continuous infrared winds during the outburst of a black hole
X-ray binaries are stellar systems composed of a compact object (either a stellar-mass black hole or a neutron star) and a donor star that transfers mass to the...
Discovery of pulsations in the nitrogen-rich PG1159 star PG 1144+005
Up to 98% of all single stars will eventually become white dwarfs - stars that link the history and future evolution of the Galaxy, and whose previous evolution...
Discovery of the highest-energy photons from a gamma-ray burst by the MAGIC telescopes
Gamma-ray bursts (GRBs) are brief and extremely powerful cosmic explosions. They are thought to result from the collapse of massive stars or the merging of...
