  • Superflares from star-planet interaction )Rubenstein and Schaefer (2000)?

  • Maehara et al. (2012):

  • Superflares on solar-type

  • stars

  • 9751 sola-type stars in

  • Kepler field

  • 365 superflares (>1035 ergs)

  • in 148 stars

  • None of them has Hot

  • Jupiter!

  • 9751 sola-type stars in Kepler field

  • 365 superflares (>1035 ergs) in 148 stars

  • One million times stronger than

  • the biggest solar flares ever obeserved.

  • Frequency is about once every

  • 5000 years

  • None of them has Hot Jupiter!

  • Could Superflares happen

  • on the Sun?



















The scientific objective of Kepler is to explore the structure and diversity of planetary systems.[45] This spacecraft observes a large sample of stars to achieve several key goals:

  • The scientific objective of Kepler is to explore the structure and diversity of planetary systems.[45] This spacecraft observes a large sample of stars to achieve several key goals:

  • To determine how many Earth-size and larger planets there are in or near the habitable zone (often called "Goldilocks planets")[46] of a wide variety of spectral types of stars.

  • To determine the range of size and shape of the orbits of these planets.

  • To estimate how many planets there are in multiple-star systems.

  • To determine the range of orbit size, brightness, size, mass and density of short-period giant planets.

  • To identify additional members of each discovered planetary system using other techniques.

  • Determine the properties of those stars that harbor planetary systems.
