The Subarcsecond Binary T Tauri Star Sample
The Taurus dark cloud is located at about 140 pc from
the Sun, so a typical angular size of a circumstellar
disk around these stars is about 1 arcsecond.
Most T Tauri stars are binaries. This paper studies
how the accretion disks around the primary and secondary
behave when the separation between the stars is comparable
to or smaller than the typical size of a disk. This combination
of HST acquisition images shows the sample. The primary and
secondary of each pair was observed spectroscopically with
STIS on HST.
