TalkPulsations in massive stars
Massive stars shape and drive our Universe. Many issues such as their formation, their stability and the mass loss effects for example, are nowadays far for...

TalkR Coronae Borealis stars and their dust
R Coronae Borealis (RCB) stars are the more prominent group of high luminosity hydrogen deficient stars that are rich in carbon and helium. They also show...

TalkRapid Temporal Survey (RaTS) - the search for ultra compact binaries
Ultra Compact Binaries are predicted to be the strongest known sources of gravitational waves in the LISA pass-band. Since they are at the short period end of...

TalkReflections on the discovery of pulsars
In this talk I will summarise the events that led to the discovery of the first four pulsars, recount several instances where pulsars were almost discovered and...

TalkRelative ages of Galactic globular clusters. Clues to the Milky Way formation time scales
Based on observations with the Advanced Camera for Surveys (ACS), I will present accurate relative ages for a sample of 64 Galactic globular clusters. This...

TalkRotational velocities in Galactic OB stars: the Fourier transform revolution
The application of the Fourier transform (FT) technique to high resolution spectra of OB-type stars has challenged our previous knowledge about stellar rotation...

TalkRubidium-rich asymptotic giant branch stars in the Magellanic Clouds
Asymptotic Giant Branch (AGB) stars are a principal source of gas and dust input into the interstellar medium, being an important driver of chemical evolution...
