Patterns of Sunlight on Extra-Solar Planets - Tony Dobrovolskis (SETITalks)
Μετάδοση με ζωντανή ροή στις 18 Μαρ 2014
Speaker: Tony Dobrovolskis, NASA Ames/SETI Institute
Exoplanets
discovered to date show a wide range of orbital eccentricities; the
angles between their spin equators and orbital planes are still quite
unknown, but these "obliquities'' may range widely as well. Both
eccentricity and obliquity can have profound effects on a planet's
seasons, as well as on its cycle of night and day. Remarkable patterns
of insolation occur on synchronously-rotating planets, and on those in
other spin-orbit states, with implications for their climates,
detectability, and habitability.
