CharlaThe CoRoT satellite and its surprising exoplanets
Up to now more than 400 extrasolar planets have been discovered, about 60 of them are transiting. Transiting extra-solar planets are particularly interesting...

CharlaThe death and afterlife of massive stars
Observations of supernovae and gamma-ray bursts show that massive stars end their lives with a wide variety of properties. For supernovae, mass loss plays a...

CharlaThe discovery of a supernova type Ia progenitor at the heart of a planetary nebula
I will report on the results of our paper published in Nature this week, outlining the discovery of a super-Chandrasekhar double-degenerate binary system at the...

CharlaThe distribution of gas and star formation in M81
In this talk I will present the first complete 12CO J=3-2 map of M81, observed as part of the Nearby Galaxies Legacy Survey. We have detected nine regions of...

CharlaThe evolution of massive contact binaries: model predictions for the Magellanic Clouds and the Milky Way
The majority of massive stars are born in close binary systems with orbital periods of a few days. At some point during their core-hydrogen burning phase, both...

CharlaThe Evolution of Massive Stars towards their Death: Rotation, Binarity and Mergers.
Although they are rare and short-lived, massive stars play a major role in Universe. With their large luminosities, strong stellar winds and spectacular...

CharlaThe fate of ionizing radiation from massive stars in star-forming galaxies
The fate of ionizing radiation from massive stars has fundamental consequences on scales ranging from the physics of circumstellar disks to the ionization state...

CharlaThe GRB-supernova connection. Or is there any?
Long suspected on theoretical grounds and supported by tantalising observational evidence, the connection between supernovae and gamma-ray bursts was definitely...
