Spitzer Secondary Eclipses of Qatar-1b [PDF]

open access: yes, 2017
Previous secondary eclipse observations of the hot Jupiter Qatar-1b in the Ks band suggest that it may have an unusually high day side temperature, indicative of minimal heat redistribution. There have also been indications that the orbit may be slightly

CamBAfx: workflow design, implementation and application for neuroimaging

open access: yesFrontiers in Neuroinformatics, 2009
CamBAfx is a workflow application designed for both researchers who use workflows to process data (consumers) and those who design them (designers). It provides a front-end (user interface) optimized for data processing designed in a way familiar to ...

Eclipses of the Sun

open access: yesAmerican Journal of Physics, 1929
The observation of a total eclipse of the sun is one of great excitement and nerve-racking tension. The life of an eclipse astronomer may be likened to that of a hunter after big game. Many months and even years are spent in quietly investigating the problems, a costly equipment is accumulated and each piece of delicate apparatus is carefully tested at

Physical Processes Driving the Response of the F2 Region Ionosphere to the 21 August 2017 Solar Eclipse at Millstone Hill

open access: yesJournal of Geophysical Research: Space Physics, 2019
The high‐resolution thermosphere‐ionosphere‐electrodynamics general circulation model has been used to investigate the response of F2 region electron density (Ne) at Millstone Hill (42.61°N, 71.48°W, maximum obscuration: 63%) to the Great American Solar ...

Broadband Radio Spectral Observations of Solar Eclipse on 2008-08-01 and Implications on the Quiet Sun Atmospheric Model

open access: yes, 2009
Based on the joint-observations of the radio broadband spectral emissions of solar eclipse on August 1, 2008 at Jiuquan (total eclipse) and Huairou (partial eclipse) at the frequencies of 2.00 -- 5.60 GHz (Jiuquan), 2.60 -- 3.80 GHZ (Chinese solar ...

Effects of Interstellar Dust Scattering on the X-ray Eclipses of the LMXB AX J1745.6-2901 in the Galactic Center [PDF]

open access: yes, 2018
AX J1745.6-2901 is an eclipsing low mass X-ray binary (LMXB) in the Galactic Centre (GC). It shows significant X-ray excess emission during the eclipse phase, and its eclipse light curve shows an asymmetric shape.

Ionospheric Total Electron Content Response to the Great American Solar Eclipse of 21 August 2017

open access: yes, 2018
Using a comprehensive database of ~4,000 ground‐based Global Navigation Satellite Systems stations, we investigate the ionosphere's response to the 21 August 2017 solar eclipse.

Characterisation of COPD heterogeneity in the ECLIPSE cohort

open access: yesRespiratory Research, 2010
BackgroundChronic obstructive pulmonary disease (COPD) is a complex condition with pulmonary and extra-pulmonary manifestations. This study describes the heterogeneity of COPD in a large and well characterised and controlled COPD cohort (ECLIPSE ...

REPEATABILITY AND ACCURACY OF EXOPLANET ECLIPSE DEPTHS MEASURED WITH POST-CRYOGENIC SPITZER [PDF]

open access: yes, 2016
We examine the repeatability, reliability, and accuracy of differential exoplanet eclipse depth measurements made using the InfraRed Array Camera (IRAC) on the Spitzer Space Telescope during the post-cryogenic mission. We have re-analyzed an existing 4.5
