The role of surface water in the geometry of Mars' valley networks and its climatic implications

Autor: Seybold, H. J., Kite, E., Kirchner, J. W.

Mars' surface bears the imprint of valley networks formed billions of years ago and their relicts can still be observed today. However, whether these networks were formed by groundwater sapping, ice melt, or fluvial runoff has been continuously debat

Possible Disintegrating Short-Period Super-Mercury Orbiting KIC 12557548

Autor: Rappaport, S., Levine, A., Chiang, E., Mellah, I. El, Jenkins, J., Kalomeni, B., Kite, E. S., Kotson, M., Nelson, L., Rousseau-Nepton, L., Tran, K.

We report here on the discovery of stellar occultations, observed with Kepler, that recur periodically at 15.685 hour intervals, but which vary in depth from a maximum of 1.3% to a minimum that can be less than 0.2%. The star that is apparently being

Over 300 extrasolar planets (exoplanets) have been detected orbiting nearby stars. We now hope to conduct a census of all planets around nearby stars and to characterize their atmospheres and surfaces with spectroscopy. Rocky planets within their sta

Fomalhaut's Debris Disk and Planet: Constraining the Mass of Fomalhaut b From Disk Morphology

Autor: Chiang, E., Kite, E., Kalas, P., Graham, J. R., Clampin, M.

Publikováno v: Astrophys.J.693:734-749,2009

Following the optical imaging of the exoplanet candidate Fomalhaut b (Fom b), we present a numerical model of how Fomalhaut's debris disk is gravitationally shaped by an interior planet. The model is simple, adaptable to other debris disks, and can b
