Description
We have obtained high resolution optical spectroscopy of the accretion
disc corona source 2S0921-630 (=V395 Car) that constrains the spectral
type of the companion star to be most probably K0iii. At 6500 Angstroms
the secondary star is found to contribute ~ 25% to the observed flux.
The absorption line spectrum of the K0iii companion star is broadened
(compared to template stars) by a projected rotational velocity of
65+/-9 km s(-1) (1-sigma ).
