Abstract:
We present the results of a 5.5-yr CCD photometric campaign that
monitored 261 bright, southern, semiregular variables (SRVs) with
relatively precise Hipparcos parallaxes. The data are supplemented
with independent photoelectric observations of 34 of the brightest
stars, including 11 that were not part of the CCD survey, and a
previously unpublished long time- series of VZ Cam. Pulsation periods
and amplitudes are established for 247 of these stars, the majority of
which have not been determined before. All M giants with sufficient
observations for period determination are found to be variable, with
87 per cent of the sample (at a signal-to-noise ratio of ≥7.5)
exhibiting multiperiodic behaviour. The period ratios of local SRVs
are in excellent agreement with those in the Large Magellanic Cloud.
Apparent K-band magnitudes are extracted from multiple near-infrared
catalogues and analysed to determine the most reliable values. We
review the effects of interstellar and circumstellar extinction and
calculate absolute K-band magnitudes using revised Hipparcos
parallaxes.
Description:
We provide Table 3 in electronic form, as well as differential
photometry for the stars in this survey.
