Descripción
The β Cephei star κ Scorpii is known to be multiperiodic from
old photometric observations. A main period of 4.8 hr was detected, and
from a beat period of about 7 d a secondary period of 4.9 hr was
calculated. These periods were also found in recently analyzed line
profile data. In two short data sets (separated by 152 d) obtained by
the star camera of the satellite WIRE (Wire-field Infrared Explorer) the
known main period of 4.8 hr is clearly present. The secondary period
could also be confirmed, although some other periodicities are present
as well. While the amplitude of the main variation is about 0.0055 mag,
the amplitude of the secondary is only 0.0014 mag. Two longer periods
(3.6 and 0.45 d) and a period of 4.2 hr were also found significant in
the WIRE data.
