摘要
In this work we have investigated spottiness of the young active K2-dwarf PW And. The spottiness analysis was based on high resolution spectroscopic observations obtained by 1.5-m Russian-Turkish telescope on September-October, 2015. The least square deconvolution technique was used to increase S/N of analyzed line profiles. The reconstruction of the spots distribution was performed by developed Doppler imaging codes. It was found that spots concentrate at intermediate latitudes.
