Denis Denisenko (born 16 January 1971) is a Russian astronomer of the late 20th – early 21st century, discoverer of 7 supernovae, more than 50 variable stars, an asteroid, and a comet.
Born in 1971 in Moscow, Denisenko graduated from Moscow Institute of Physics and Technology (MIPT or Phystech) in 1993 with a Master of Science in Astrophysics and a Diploma: Spectral Properties of Gamma-Ray Bursts Observed by PHEBUS Instrument of the Granat observatory. In 1991, he joined the High Energy Astrophysics Department of the Russian Space Research Institute (IKI) where he worked until April 2012. He was a visiting observer at the TUBITAK National Observatory (TUG) between 2002 and 2007. Since May 2012 he works at the Space Monitoring Laboratory of Sternberg Astronomical Institute of Moscow State University (SAI MSU). He is the author of more than 30 scientific articles, 250 astronomical telegrams and the presenter of talks at several international conferences.
He has been an amateur astronomer since 1977, a member of the Moscow Astronomy Club since 2002 and the head of a working group on asteroidal occultations. He participated in Astrofests 2001–2006 and was a speaker at Astrofest 2005, 2006 and 2013. He is an active enthusiast of professional-amateur collaboration in astronomy and long-time contributor to IOTAoccultations, Planoccult, meteorobs, comets-ml, MPML, SeeSat, AAVSO-HEN, AAVSO-DIS, vsnet-alert, vsnet-outburst, cvnet-discussion mailing lists. He is the owner and moderator of five Russian astronomy mailing lists (komety, pokrytie, rusmeteors, moscow-astro, varstars) and author of a few popular articles in Zemlya i Vselennaya (Earth and Universe) magazine. He was mentioned in Sky and Telescope twice and gave interviews on Russian News Service, Radio Liberty, Gazeta.ru newspaper, and the BBC Russian Service in 2007.
