DIVERSITY OF EXTRASOLAR PLANETS AND DIVERSITY OF MOLECULAR CLOUD CORES. I. SEMIMAJOR AXES

phylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...

Extrasolar Planets Jonathan I

NOTES: (a) JWST numbers appropriate to the assumptions in their updated Science Requirements Document must be calculated; (b) the GSMT sensitivity calculations must be ‘scrubbed’ to ensure that the assumptions re detectors; atmosphere; emissivity are duly conservative; and (c) the expected. performance of the JWST NIR coronagraph needs to be folded in. Please review with these caveats in mind (...

A link between the semimajor axis of extrasolar gas giant planets and stellar metallicity

The fact that most extrasolar planets found to date are orbiting metal-rich stars lends credence to the core accretion mechanism of gas giant planet formation over its competitor, the disk instability mechanism. However, the core accretion mechanism is not refined to the point of explaining orbital parameters such as their unexpected semimajor axes and eccentricities. We propose a model, which ...

Evaporation of extrasolar planets

Atomic hydrogen escaping from the extrasolar giant planet HD209458b provides the largest observational signature ever detected for an extrasolar planet atmosphere. In fact, the upper atmosphere of this planet is evaporating. Observational evidences and interpretations coming from various models are reviewed. Implications for exoplanetology are discussed.
