Sara Seager (born 21 July 1971) is a Canadian-American Astronomer and planetary scientist . [2] She is a professor at the Massachusetts Institute of Technology and Berninahaus for re work on extrasolar planets en hun Atmospheres. She is the author of two text books on synthesis topics. [5] [6] She has leg honored for this research by Popular Science , [7]Discover Magazine , [8] Nature , [9] and TIME Magazine . [10] Seager was Awarded a MacArthur Fellowship in 2013 Citing re theoretical work on Detecting chemical signatures on exoplanet Atmospheres and ontwikkelingslanden low-cost space Observatories to observe planetary transit traffic . [11]

Background

Seager was born in Toronto, Ontario , Canada . [2] Her Father, Dr. David Seager was a pioneer in hair transplantation and the founder of the Seager Hair Transplant Center in Toronto. [12]

She earned the degree of Bachelor of Science in Mathematics and Physics from the University of Toronto in 1994 assisted by a NSERC University Undergraduate Student Research Award and a Ph.D. in astronomy from Harvard University in 1999. Her doctoral thesis developed theoretical models or Atmospheres on extrasolar planets, and was supervised by Dimitar Sasselov . [3] [4] [13] She held a Postdoctoral research fellow position at the Institute for Advanced Study tussen 1999 en 2002 and a senior research staff member at the Carnegie Institution of Washington Until 2006. She joined the Massachusetts Institute of Technology in January 2007 as an associate professor of physics and zowel planetary science, was granted tenure in July 2007, [14] and was elevated to full professor in July 2010. [15] She Currently holds the “Class of 1941” chair. [1]

She is married to husband Charles Darrow and they ‘have two sons from re first marriage. Her deceased first spouse, Michael Wevrick, mayest or cancer in 2011. [16] [17]

Academic research

NASA ‘s PlanetQuest referred to as re “an Astronomical Indiana Jones”. [18] Sarah Seager-used the term “gas dwarf” for a high-mass super-Earth type planet Composed Mainly or Hydrogenation and helium in an animation of one model of the exoplanet Gliese 581 c . The term “gas dwarf” has ook leg-used to refer to planets narrower dan gas giants , with thick Hydrogenation and helium Atmospheres. [19] [20]

Seager was Awarded the 2012 Sackler Prize for “analysis of the Atmospheres and internal Compositions or extra-solar planets”, [21] the Helen B. Warner Prize from the American Astronomical Society in 2007 for ontwikkelingslanden “fundamental techniques for understanding, analyzing, and finding the Atmospheres of extrasolar planets. [22] and the 2004 Harvard Bok Prize in Astronomy. [23] She was appointed as a fellow to the American Association for the Advancement of Science in 2012 and elected to the Royal Astronomical Society of Canada as an honorary member in 2013. [1] in September 2013 she became a MacArthur Fellow . [24]

Seager equation

Seager developed a parallel version of the Drake equation to estimate as the number of habitable planets in the galaxy. [25] Limit download aliens with radio technology, Seager has revised the Drake equation to focus on simply the presence or Any alien life detectable from Earth. The equation focuses on the search for planets with biosignature gases, gases produktie to life dat kan accumulate in a planetary atmosphere to levels die kunnen worden detected with remote space telescopes. [25]

N = N * F Q F HZ F o F L F S

where: N = the number of planets with detectable signs of life

N * = the number of stars Observed

F Q = the group or stars therein are quiet

F HZ = the group or stars with rocky planets in the habitable zone

F o = the group or Those planets die kunnen worden Observed

F L = the political group therein harbor life

F S = the political group on welke life produces a detectable signature gas
