Exoplanet Exploration James Kelly Mitchell Kirshner Adam Morabito Matt Rote
Exoplanets • • • Planets outside of our solar system Need to differentiate from other celestial bodies. Criteria: Must orbit star or star remnants. o Mass must be less than limiting mass for thermonuclear reaction of deuterium. o Mass to size ratio is the same as our solar system. o
Why do they matter? • • Understanding our solar system Finding habitable planets Search for signs of possible life Isolate our search for intelligent life
So Far. . . • • 1988: First discovered exoplanet around Gamma Cephei. Programs: Super. Wasp o Kepler mission o ESPRESSO o HATNet Project o • 888 planets in 693 systems Most larger than Earth o 2, 781 candidates o 28 potentially habitable exoplanets o 38 potentially habitable exomoons o
The Future • • Automated Planet Finder Terrestrial Planet Finder Gaia mission New Worlds Mission
Terrestrial Planet Finder • • Proposed in 2002 Approved in 2004 Suspended in 2007 Goals – Find Extrasolar Planets – Characterize Planets – Chemical Signatures of Life • Architectures – TPF-I – TPF-C
TPF-I • • Infrared Astronomical Interferometer Multiple Small Telescopes Uses Nulling Drawback: Limited Resolution
TPF-C • • Visible Light Coronagraph Large Optical Telescope Uses Special Optics Comparison to Hubble
Budget • Entire Budget = $1 billion • Assumption: – TPF-I = $500 million – TPF-C = $500 million • Comparison to Hubble Replacement • Fund TPF-C, Not TPF-I
Kepler Mission • March 7, 2009 • 100, 000 stars near Cygnus • Predict # of Earth-like planets in galaxy • Transit Method – Small Planets • Photometer
Malfunction/Budget • This past Sunday • $18. 7 Million – $600 Million • 2016 – Transiting Exoplanet Survey Satellite
Hubble Space Telescope • April 24, 1990 • High powered optics • Fomalhaut b – 2004 • Decades of data • James Webb Space Telescope
Budget • • $96. 3 Million Servicing missions Expected to function until 2013 2018
Conclusion • Exoplanet Importance • The Past • The Future
Programs and Cuts • TPF • Kepler • Hubble
