The vast
researches carried out in the field of variable eclipsing stars photometry, all over the world, has effectively assisted the completion of the
star evolution in the binary systems theory.
Fortunately, Biruni observatory considering
the instruments with which it is equipped, is able to provide the opportunity
for the extensive research in this field. Since the beginning of the functioning
of this observatory, many stars have been studied with this method. Some
samples of researches carried out in this field are given further below.
These researches have been done using the 51-cm telescope and the
related photometer :

Teoretical research is also carried out on the following topics:
- Cosmological models
- Theories of gravitation
- Cosmological defects
- Neutron stars (structure and equation of state)
