Abstract:
We present accurate photometric time series of two Be stars: NW Ser
and V1446 Aql. Both stars were observed at the Observatorio de Sierra
Nevada (Granada) in July 2003 with an automatic four-channel
Stroemgren photometer. We also present a preliminary theoretical study
showing that the periodic variations exhibited by these stars can be
due to pulsation.
Description:
We present differential photometry in the Stromgren filters uvby for
the Be stars NW Ser (Table A1) and V1446 Aql (Table A2).
