Spitzer Transit and Secondary Eclipse Photometry of GJ 436b
We report the results of infrared (8 μm) transit and secondary eclipse photometry of the hot Neptune exoplanet, GJ 436b using Spitzer. The nearly photon-limited precision of these data allows us to…

Observations of the infrared spectrum of the transiting extrasolar planet HD 209458b reveal a hot thermal continuum for the planetary spectrum, with an approximately constant ratio to the stellar flux over this wavelength range.
Acquisition order and resource value in Cuscuta attenuata.
Field observations showed that in its native Texas grasslands, dodder grows more vigorously in patches of mixed host species than in monospecific host patches, and Sodium, acting as an osmoticum, is implicated as the factor responsible for experimentally produced as well as observed field patterns.
