Active Galactic Nuclei: Sources for ultra high energy cosmic rays?
P. L. Biermann, J. K. Becker, L. Caramete +11
The origin of ultra high energy cosmic rays promises to lead us to a deeper understanding of the structure of matter. This is possible through the study of particle collisions at c…
Binarity and multiperiodicity in high-amplitude delta Scuti stars
A. Derekas, L. L. Kiss, T. R. Bedding +10
We have carried out a photometric and spectroscopic survey of bright high-amplitude delta Scuti (HADS) stars. The aim was to detect binarity and multiperiodicity (or both) in order…
A Catalog of 24um Sources Toward the Galactic Center
J. L. Hinz, G. H. Rieke, F. Yusef-Zadeh +3
We present a 1.5deg x 8deg (220pc x 1195pc) Multiband Imaging Photometer for Spitzer 24um image of the Galactic Center and an accompanying point source list. This image is the high…
An extensive photometric study of the Blazhko RR Lyrae star MW Lyr: II. Changes in the physical parameters
J. Jurcsik, Á. Sódor, B. Szeidl +11
The analysis of the multicolour photometric observations of MW Lyr, a large modulation amplitude Blazhko variable, shows for the first time how the mean global physical parameters…
AAOmega radial velocities rule out current membership of the planetary nebula NGC 2438 in the open cluster M46
L. L. Kiss, Gy. M. Szabo, Z. Balog +2
We present new radial velocity measurements of 586 stars in a one-degree field centered on the open cluster M46, and the planetary nebula NGC 2438 located within a nuclear radius o…
Photoevaporation of Protoplanetary Disks
Z. Balog, G. H. Rieke, J. Muzerolle +4
We present HST/NICMOS Paschen alpha images and low and high resolution IRS spectra of photoevaporating disk-tail systems originally detected at 24 micron near O stars. We find no P…
