HD 77407 and GJ 577: Two new young stellar binaries
Astronomy and Astrophysics
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 with the 3.5 m Calar Alto telescope and the AO system ALFA. With two epoch observations which were separated by about one year, we found two co-moving companion candidates, one close to HD 77407 and one close to GJ 577. For the companion candidate near GJ 577, we obtained an optical spectrum showing spectral typedoi:10.1051/0004-6361:20040008 fatcat:zz4z4fygenbyvifgihbom6npae
