Discovery of a New [WR] Star

Popis výsledku v původním jazyce

Wolf-Rayet (WR) stars are evolved massive objects, famous for their spectra rich with emission lines. For the first time WR stars were described more than 150 years ago, and now in our Galaxy we know around 667 objects of this type. However, the discovery of a new WR star, especially based on spectral observations, is still a rare event. The paper is devoted to J040901.83+323955.6 star, discovered a few years ago as WR star in LAMOST spectral survey by machine learning methods. We were interested thatifferent researchers based on different methods classify this object in different ways - ranging from RR Lyr variable to nitrogen rich WR - and so we began our study. We combined spectral and archival photometric data, analysed the spatial location of the star in the Galaxy and concluded what J040901 is [WR] - central star of a planetary nebula.
