A new look at NICMOS transmission spectroscopy of HD189733, GJ-436 and XO-1: no conclusive evidence for molecular features
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/28
We present a re-analysis of archival HST/NICMOS transmission spectroscopy of three exoplanet systems; HD 189733, GJ-436 and XO-1. Detections of several molecules, including H20, CH4 and CO2, have been...
Distinctive features of ion-acoustic solitons in EPI super-dense magneto-plasmas with degenerate electrons and positrons
Solar and Stellar Astrophysics (astro-ph.SR) Plasma Physics (physics.plasm-ph)
2010/12/23
Using the extended Poincar\'{e}-Lighthill-Kuo (PLK) reductive perturbation method to study the small-amplitude ion acoustic solitary wave (IASW) dynamics (propagation and interaction), it is shown tha...
Absorption Features in Spectra of Magnetized Neutron Stars
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/23
The X-ray spectra of some magnetized isolated neutron stars (NSs) show absorption features with equivalent widths (EWs) of 50 - 200 eV, whose nature is not yet well known.
Evidence of Decay of Flux Ratio of Fe to Fe–Ni Line Features with Electron Temperature in Solar Flares
Sun flares corona—X-rays
2010/9/15
We report observational evidence of the decay of the flux ratio of Fe to Fe–Ni line features as a function of plasma electron temperature in solar flares in comparison to that theoretically predicted ...
Radiative emission of solar features in Ca II K
Sun full-disk observations Sun atmosphere Sun magnetic fields
2010/3/9
We investigated the radiative emission of different types of solar features in the spectral range of the Ca II K line.
We analyzed full-disk 2k x 2k observations from the PSPT Precision Solar Photom...
