Biography:

He was born on August 31, 1930 in the Ochakiv city in Nikolaev region of Ukrainian SSR in a family of employees.

In 1948 he entered the I. I. Mechnikov State Odessa University, who graduated with honors in 1953 with a degree in Astronomy, but only in 1960 received a job in Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR. He started his career in Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR from the post of senior laboratory assistant. Since June of the same year he worked as an engineer, since 1962 - Junior, since 1972 - senior, and since 1986 - a leading researcher.

His scientific interests concern astro-spectroscopy, the study of nonstationary vision, physical conditions in their atmospheres. In 1967 he defended his Ph.D. thesis on "Physical Conditions in the Atmosphere of μ Ser (Cephei) and Other Supergiants of the Spectral Class M" at the Odessa University. Along with the study of spectra of late giant stars and supergiants, he also studied the spectra of new stars and one of the first to determine the rate of expansion of their membranes in the first weeks after the outbreak. The group of employees of the Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR under his leadership was one of the first in the former USSR to master the calculations of the synthetic spectra of the stars of late spectral classes. It was he who instructed his students to master the most relevant scientific areas of his time - the analysis of molecular spectra of stars and automation of processing of stellar spectra and non-LTE calculations. Under the direction of M.Ya. Orlov successfully defended the candidate's theses of two employees of Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR.

Since 1975, he coordinated collaborative studies of non-stationary vision type R of the Northern Crown. He participated in the monograph "Star of the R-type of the Northern Crown" (Russian). He was the head of the problem-thematic group "AstroSpectroscopy", a member of the working group of Astrocouncil of the Academy of Sciences of the USSR "Star atmospheres", a member of the problem commission of multilateral cooperation of the member countries of the KIEV "Physics and evolution of vision" and a member of the International Astronomical Union since 1979.

He contributed to the creation of an astrophysical branch of the Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR. In the early 1960s, he took part in the selection of a place for a branch, making preliminary intelligence in some regions of Ukraine. And in 1971 he was one of the first observers at AZT-24 on the peak of Terskol (Elbrusya) to find out the astroclimatic conditions there. It was instructed him to conduct the first talks with representatives of the firm Carl Zeiss on the acquisition of a 2-M telescope for this branch, which eventually successfully resolved.

Another direction of M.Ya. Orlov's activity is publishing. During 1977-1984 pp. He was deputy editor-in-chief of the collection Astrometry and Astrophysics, and during 1985-1998 pp. He was Deputy Chief Editor of the journal "Kinematics and Physics of Celestial Bodies". In 2004, he published the Astronomical Encyclopedic Dictionary, which he also edited.

Since January 1992, he served as the head of the editorial and publishing department of the Main Astronomical Observatory of the Academy of Sciences of the Ukrainian SSR, while remaining at the forefront of a research fellow on a voluntary basis. In July 1998, the astronomer retired.

On July 11, 2004 he died.
