Abstract:
Gorga (1971) investigated the binary nature of the star HD 91948 (=BD+60d
1274 = SAO 15243; F8V). He found it to be a spectroscopic binary with an
orbital period of 2.7700266d. The first photoelectric (UBV) observations were
carried out by Padalia (1980) from May 1973 to May 1978 on 17 nights to see its
variable (eclipsing binary) nature. However, Padalia (1980) found the
variability of this star only on two nights (falling at phases 0.09d and 0.25d),
though the star had been observed almost in the entire phase region. It was
concluded that the star was a suspected variable and not an eclipsing binary.
From his photoelectric observations he determined its spectral type to be
A0V.
