Towards characterization of exoplanetary atmospheres with the VLT Interferometer
Viki Joergens, Andreas Quirrenbach
The direct observation of extrasolar planets and their spectra is coming into reach with the new generation of ground-based near-IR interferometers, like the Very Large Telescope I…
Modeling of Closure Phase Measurements with AMBER/VLTI - Towards Characterization of Exoplanetary Atmospheres
Viki Joergens, Andreas Quirrenbach
Differential phase observations with a near-IR interferometer offer a way to obtain spectra of extrasolar planets. The method makes use of the wavelength dependence of the interfer…
Dynamics of the circumstellar gas in the Herbig Ae stars BF Orionis, SV Cephei, WW Vulpeculae and XY Persei
A. Mora, C. Eiroa, A. Natta +22
We present high resolution (lambda / Delta_lambda = 49000) echelle spectra of the intermediate mass, pre-main sequence stars BF Ori, SV Cep, WW Wul and XY Per. The spectra cover th…
Study of the properties and spectral energy distributions of the Herbig AeBe stars HD 34282 and HD 141569
B. Merín, B. Montesinos, C. Eiroa +5
We present a study of the stellar parameters, distances and spectral energy distributions (SEDs) of HD 34282 and HD 141569, two pre-main sequence Herbig AeBe stars. Both objects ha…
