New Luminous Blue Variable Candidates in NGC 4736
  We have found three new LBV candidates in the star-forming galaxy NGC 4736.
They show typical well-known LBV spectra, broad and strong hydrogen lines, He I
lines, many Fe II lines, and forbidden [Fe II] and [Fe III]. Using archival
Hubble Space Telescope and ground-based telescope data, we have estimated the
bolometric magnitudes of these objects from -8.4 to -11.5, temperatures, and
reddening. Source NGC 4736_1 (Mv = -10.2 +/- 0.1 mag) demonstrated variability
between 2005 and 2018 as Delta V = 1.1 mag and Delta B = 0.82 mag, the object
belongs to LBV stars. NGC 4736_2 (Mv < -8.6 mag) shows P Cyg profiles and its
spectrum has changed from 2015 to 2018. The brightness variability of NGC
4736_2 is Delta V = 0.5 mag and Delta B = 0.4 mag. In NGC 4736_3 (Mv = -8.2 +/-
0.2 mag), we found strong nebular lines, broad wings of hydrogen; the
brightness variation is only 0.2 mag. Therefore, the last two objects may
reside to LBV candidates.
