A detailed study of the nuclear region of Mrk 273
M. Bondi, D. Dallacasa, M. A. Peerez Torres +1
We present 5 GHz EVN+MERLIN observations of the nuclear region of the ultra luminous infrared galaxy Mrk 273. These observations confirms the detection, on the mas scale, of two re…
Multi-wavelength differential astrometry of the S5 polar cap sample
J. C. Guirado, J. M. Marcaide, E. Ros +2
We report on the status of our S5 polar cap astrometry program. Since 1997 we have observed all the 13 radio sources of the complete S5 polar cap sample at the wavelengths of 3.6 c…
Internal Kinematics of Microstructures and Implications
Luis F. Miranda
High resolution images at different wavelengths show the common presence of structures and microstructures in planetary nebulae (PNe), which are not well incorporated to the existi…
Photometry of Be Stars in the vicinity of COROT primary targets for asteroseismology
J. Gutierrez-Soto, J. Fabregat, J. Suso +3
We present differential photometry of Be stars close to potential COROT primary targets for asteroseismology. Several stars are found to be short period variables. We propose them…
Analysis of Balmer Profiles of early type stars
Mercedes Molla, Angeles I. Diaz, Mar Alvarez Alvarez +1
The spectral energy distribution (SED) of recent star formation regions is dominated by the more massive and early stars (O and B types). These stars show large and very significan…
WNB 0313+683: Analysis of a Newly Discovered Giant Radio Galaxy
A. P. Schoenmakers, K. -H. Mack, L. Lara +4
We present the results of a detailed analysis of the newly discovered 15 arcmin large FRII-type radio galaxy WNB 0313+683. It has a redshift of 0.0901 +/- 0.0002 and a projected li…
