Abstract:
We analysed space photometry from the TESS mission for a sample of
1002 mCP stars discovered in LAMOST archival spectra. Of the 782 mCP
stars with available TESS data, rotation periods were measured for 720
of these. The sample includes 25 stars with additional photometric
variability, and 4 eclipsing binaries. With our work, we increase the
sample size of mCP stars with known rotation periods and identify
prime candidates for detailed follow-up studies. This enables two
paths towards future investigations: population studies of even larger
samples of mCP stars, and detailed characterisation of high-value
targets.
Description:
Rotational periods and peak-to-peak photometric amplitudes, as
measured from TESS photometry, are reported for 720 mCP stars out of
the 782 stars observed by TESS. Catalog identifiers, sky coordinates,
and spectral types are also listed. Remarks accompany stars which were
previously reported as variable, have additional non-rotational
signals, and/or to note potential issues with the data.

variability, except when n_Per = '-' for stars with problematic data.
Note (3): Considering known variables, indicating when data is of poor quality,
when additional signals exist, or when other (non-rotational)
variability is due to blending from nearby stars
