Two new LBV candidates in the galaxy IC342

Abstract

Two LBV candidates have been found in the galaxy IC342. Within the framework of the program of searching for LBV stars in galaxies outside the Local Group, spectral and photometric observations were carried out with the 6-m telescope of SAO RAS. These two objects revealed observed features characteristic of LBV stars. Their spectra show typical LBV emission lines: the broad and strong hydrogen lines and the HeI, FeII, and [FeII] emissions. We have obtained the estimates of the interstellar reddening and the photosphere temperatures. For one star, it was possible to build the spectral energy distribution (SED) and determine the temperature more accurately. We estimated the absolute magnitudes as 𝑀 𝑣 ≈ − 9 . 3 𝑚 and − 10 . 8 𝑚 , which allows us to classify the stars as LBV candidates.
