Astronomy at Heidelberg University ZAH-ITA ZAH-ARI ZAH-LSW MPIA MPIK HITS Altstadt HdA

Center for Astronomy Heidelberg (ZAH) Astronomy at Heidelberg University Institute for Theoretical Astrophysics (ITA) Cosmology (Group Bartelmann) Star Formation (Group Klessen) Planet Formation (Group Dullemond) Astronomical Calculational Institute (ARI) Galactic Neighborhood (Group Grebel) Gravitational Lensing (Group Wambsganß) Cosmology (Group Schäfer) State Observatory (LSW) Galactic Archeology (Group Christlieb) Instrumentation (Group Quirrenbach) Shown here: Only groups of full professors There are in total 23 groups Heidelberg Institute for Theoretical Studies (HITS) Funded by the Tschirra Stiftung Computational Astrophysics (Group Springel)

(Exo-)Planet(-Formation) at ZAH Institute for Theoretical Astrophysics (ITA) Planet formation (Group Dullemond) Protoplanetary dust (Group Gail) Astronomical Calculational Institute (ARI) Exoplanets by microlensing (Group Wambsganß) N-body Astrophysics (Group Spurzem) State Observatory (LSW) CARMENES (Group Quirrenbach)

Example from Microlensing (Group Wambsganß) Cassan et al. 2012, Nature Conclusion: There must be many undetected low-mass planets (Neptunes). Quote: „One or more bound planets per Milky Way star from microlensing observations“

Example from N-body (Group Spurzem) A Hybrid method of planet formation modeling: - Many small particles = statistical methods - Few big particles = N-body

Example from dust growth (Group Dullemond) How to break through the meter-size barrier. Low sticking efficiency Particle abundance Windmark, Birnstiel, Güttler, Blum, Dullemond, Henning 2012

Example from dust growth (Group Dullemond + Grenoble) Comparing with observations Pinilla, Benisty & Birnstiel (2012)

Example from asteroids (Group Gail) Henke, Gail, Trieloff, Schwarz, Kleine (2012)

Example from RV planet detection (Group Quirrenbach)
