Abstract
UBV broadband photoelectric photometry of dwarf cepheid DY Pegasus is presented. Using the observed light variations of this pulsating variable, mass, radius, gravity and temperature variations over a pulsational cycle have been estimated and its evolutionary nature is briefly discussed.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
