We present a study based on the high-resolution spectroscopy and K2 space photometry of five chemically peculiar stars in the region of the open cluster M44. The analysis of the high-precision photometric K2 data reveals that the light variations in HD73045 and HD76310 are rotational in nature and caused by spots or cloud-like co-rotating structures, which are nonstationary and short-lived. The time-resolved radial velocity measurements, in combination with the K2 photometry, confirm thatโ€ฆย
