Characterisation of the magnetic field of the Herbig Be star HD 200775
E. Alecian, C. Catala, G. A. Wade +9
After our recent discovery of four magnetic Herbig stars, we have decided to study in detail one of them, HD 200775, to determine if its magnetic topology is similar to that of the…
Hydrogen Isocyanide in Comet 73P/Schwassmann-Wachmann (Fragment B)
D. C. Lis, D. Bockelee-Morvan, J. Boissier +3
We present a sensitive 3-sigma upper limit of 1.1% for the HNC/HCN abundance ratio in comet 73P/Schwassmann-Wachmann (Fragment B), obtained on May 10-11, 2006 using Caltech Submill…
Near-IR internetwork spectro-polarimetry at different heliocentric angles
M. Jesus Martinez Gonzalez, A. Asensio Ramos, A. Lopez Ariste +1
The analysis of near infrared spectropolarimetric data at the internetwork at different regions on the solar surface could offer constraints to reject current modeling of these qui…
FADE, an instrument to measure the atmospheric coherence time
A. Tokovinin, A. Kellerer, V. Coude Du Foresto
After proposing a new method of deriving the atmospheric time constant from the speed of focus variations (Kellerer & Tokovinin 2007), we now implement it with the new instrument,…
Water in Comet 2/2003 K4 (LINEAR) with Spitzer
Charles E. Woodward, Michael S. Kelley, Dominique Bockelee-Morvan +1
We present sensitive 5.5 to 7.6 micron spectra of comet C/2003 K4 (LINEAR) obtained on 16 July 2004 (r_{h} = 1.760 AU, Delta_{Spitzer} = 1.409 AU, phase angle 35.4 degrees) with th…
Quasi-classical rate coefficient calculations for the rotational (de)excitation of H2O by H2
A. Faure, N. Crimier, C. Ceccarelli +3
The interpretation of water line emission from existing observations and future HIFI/Herschel data requires a detailed knowledge of collisional rate coefficients. Among all relevan…
