Tri L. Astraatmadja

Tri L. Astraatmadja is a postdoctoral researcher at Department of Terrestrial Magnetism, Carnegie Institution for Science, Washington, D.C.

Tri L. Astraatmadja obtained a BSc in astronomy from the Department of Astronomy of the Bandung Institute of Technology, Indonesia, after having succesfully defended his Bachelor's thesis about a calculation of the local stellar kinematics using Hipparcos data. Tri later moved to Leiden, The Netherlands, to pursue a master study at Leiden Observatory. In Leiden he worked under the supervision of Anthony Brown and Yuri Levin to develop search criteria to detect hypervelocity stars using astrometric data. His Master's thesis was supervised by Koen Kuijken, in which he performed a photometric and kinematical analysis of stars in the Galactic Bulge, using data obtained by the Hubble's Wide Field Planetary Camera 2 (WFPC2). He obtained his MSc degree in 2008.

In the same year he started his PhD research at Nikhef Amsterdam and the Physics Department of Leiden University. Together with Maarten de Jong and The ANTARES Collaboration, he tried to detect TeV gamma-rays using the ANTARES Neutrino Telescope. The search was unsuccessful, but the method and analysis has been written for posterity, and nevertheless he obtained his PhD degree.

In September 2012, he joined the Gaia CU8 Group at the Max-Planck-Institut für Astronomie (MPIA) in Heidelberg, Germany, as a postdoctoral researcher. He managed the Multiple Stellar Classification (MSC) package, a software developed to estimate the astrophysical parameters of binary stars observed by Gaia.
