What are the temperatures of T Tauri stars? - Constraints from coeval formation of young eclipsing binaries
M. Ammler, V. Joergens, R. Neuhaeuser
We show how the assumption of coeval formation can be used to constrain the effective temperatures of the components of young eclipsing double-lined spectroscopic binaries. Our met…

HD 77407 and GJ 577: two new young stellar binaries detected with the Calar Alto Adaptive Optics system ALFA
M. Mugrauer, R. Neuhäuser, E. W. Guenther +9
We present the first results from our search for close stellar and sub-stellar companions to young nearby stars on the northern sky. Our infrared imaging observations are obtained…
