Radial velocities of cool stars with rocky planets


Inicio: 12:15h
Ponente: Manuel Perger (Institut de Ciencies de l'Espai (CSIC-IEEC))
Lugar: Sala Alberto Lobo (ICE building, Campus UAB)

We are already able to detect potentially habitable, rocky planets with the precision of modern Doppler spectroscopy. At least if they orbit a low-mass star. In this domain however, magnetic phenomena of the host star affect the measurements and are even able to hide and mimic a true planetary signal.…

We are already able to detect potentially habitable, rocky planets with the precision of modern Doppler spectroscopy. At least if they orbit a low-mass star. In this domain however, magnetic phenomena of the host star affect the measurements and are even able to hide and mimic a true planetary signal. A challenge in modern radial velocity planet searches is therefore the understanding of the different stellar contributions. In this talk I will explain how we measure and obtain high-precision radial velocities and how we can disentangle the different contributions. With this focus, I will discuss in length the recent findings of exoplanets like Proxima Centauri b, GJ 3998b,c, GJ 3942b, and will give previews on my recent research target.
