X-Ray and Optical Observations of the Young M Dwarf Dipper Star TIC 234284556.

Abstract (from CDS):

We observed TIC 234284556 in X-rays and in the optical with XMM-Newton to study the recurring dip previously seen in TESS observations. The dip did not appear during our observation. We detect X-ray flares and anti-correlated rotational modulation in X-rays and in the optical.

Journal keyword(s): M dwarf stars - Stellar coronae - Stellar flares - Starspots - X-ray stars
