H 3-75: The Planetary Nebula with the Binary Central Star NSV 16624

H 3-75 is a medium-excitation planetary nebula with a binary central star consisting of a hot subdwarf with K and a cool giant. We present the results of our photometric and spectroscopic observations obtained in 2020 and analyze data from the literature. The brightness of the cool component of the...

Summary:H 3-75 is a medium-excitation planetary nebula with a binary central star consisting of a hot subdwarf with K and a cool giant. We present the results of our photometric and spectroscopic observations obtained in 2020 and analyze data from the literature. The brightness of the cool component of the binary system has been measured in the bands. We have measured the relative intensities of emission lines in the spectrum of the planetary nebula H 3-75, estimated the extinction, and determined the gaseous envelope parameters. We have found the spectral type and luminosity class of the cool star to be K0 III and analyzed its spectrum. We have estimated the distance to the object ( pc) and the luminosities of the components of the binary system: and . The hot subdwarf’s parameters and place the star on the cooling track of post-AGB stars.
