Olga V. Zakhozhay

Dr. Olga V. Zakhozhay

In 2007 year she graduated from the V.N. Karazin National University (physics department, astronomical specialty), with an honours degree.

In the period 2007-2011, she was a graduate student of the Main Astronomical Observatory National Academy of Sciences of Ukraine. In 2011she has successfully defended her Ph.D. thesis titled “Spectral energy distribution peculiarities of systems with circumsubstellar disks”.

In the period 2011-2012, she was a junior researcher and since 2013 - a researcher at the Main Astronomical Observatory National Academy of Sciences of Ukraine in the planetary systems physics department.

In 2008 she worked on the project “A UVES atlas of emission line profiles in young stellar and substellar objects” at The European Southern Observatory – ESO (Short-term visitorship supported by the Director General Discretionary Found) under the supervision of Fernando Comerón.

In 2013 she worked on the project “Spectral energy distributions of fragmenting protostellar disks” at the Institute for Astrophysics, University of Vienna (supported by the Austrian Agency for International Cooperation in Education and Research, OeAD) in collaboration with Eduard Vorobyov.

She gave talks at the seminars in:

  • Main Astronomical Observatory of NAS of Ukraine (Kyiv, Ukraine, 2008 – 2014),
  • Institute of Astrophysics, University of Vienna (Vienna, Austria, 2013),
  • Institute of Radio Astronomy of NAS of Ukraine (Kharkiv, Ukraine, 2011),
  • Astronomical Institute of the Ruhr University (Bochum, Germany, 2010 and 2011).

She participated in international conferences and schools that took part in Ukraine, Croatia, the Vatican, Italy, Great Britain, Spain, Portugal, Germany, Austria, the United States, Armenia, Slovakia, Brazil, China and France.

Scientific interests: planetary, substellar, and stellar formation, exoplanets, low-mass stellar and substellar objects.
