X-ray supernova remnants in nearby galaxies
Ioanna Leonidaki, Andreas Zezas, Panayotis Boumis
We present the initial results from a study of the SNR population in a sample of six nearby galaxies (NGC 2403, NGC 4214, NGC 4449, NGC 5204, NGC 3077, NGC 4395) based on Chandra a…
A principal component analysis approach to the morphology of Planetary Nebulae
Stavros Akras, Panayotis Boumis
Principal Component Analysis (PCA) is a well-known technique used to decorrelate a set of vectors. It has been applied to explore the star formation history of galaxies or to deter…
FUV Spectroscopy of the sdOB Primary of the Eclipsing Binary System AA Dor
Johannes Fleig, Thomas Rauch, Klaus Werner +1
AA Dor is an eclipsing, close, post common-envelope binary (PCEB). We present a detailed spectral analysis of its sdOB primary star based on observations obtained with the Far Ultr…
HAT-P-6b: A Hot Jupiter transiting a bright F star
R. W. Noyes, G. A. Bakos, G. Torres +17
In the ongoing HATNet survey we have detected a giant planet, with radius 1.33 +/- 0.06 RJup and mass 1.06 +/- 0.12 MJup, transiting the bright (V = 10.5) star GSC 03239-00992. The…
Quasar optical variability and black hole mass
M. Wold, M. S. Brotherton, Z. Shang
In order to investigate the dependence of quasar optical-UV variability on fundamental physical parameters like black hole mass, we have matched quasars from the QUEST1 variability…
Tidal tails around globular clusters
M. Montuori, R. Capuzzo-Dolcetta, P. Di Matteo +1
We present the results of detailed N-body simulations of clusters moving in a realistic Milky Way (MW) potential. The strong interaction with the bulge and the disk of the Galaxy l…
