Dynamics of isolated magnetic bright points derived from Hinode/SOT G-band observations

D. Utz, A. Hanslmeier, R. Muller +3

Small-scale magnetic fields in the solar photosphere can be identified in high-resolution magnetograms or in the G-band as magnetic bright points (MBPs). Rapid motions of these fie…

The spectroscopic evolution of the symbiotic star AG Draconis. I.The O VI Raman, Balmer, and helium emission line variations during the outburst of 2006-2008

S. N. Shore, G. M. Wahlgren, K. Genovali +6

AG Dra is one of a small group of low metallicity S-type symbiotic binaries with K-type giants that undergoes occasional short-term outbursts of unknown origin. Our aim is to study…

Searching for flickering statistics in T CrB

A. Dobrotka, L. Hric, J. Casares +3

We analyze -band photometry of the aperiodic variability in T CrB. By applying a simple idea of angular momentum transport in the accretion disc, we have developed a method to s…

Magnetic loop emergence within a granule

P. Gömöry, C. Beck, H. Balthasar +4

We investigate the temporal evolution of magnetic flux emerging within a granule in the quiet-Sun internetwork at disk center. We combined IR spectropolarimetry performed in two Fe…

The 2008 August 1 Eclipse Solar-Minimum Corona Unraveled

Jay M. Pasachoff, Vojtech Rusin, Miloslav Druckmuller +3

We discuss results stemming from observations of the white-light and [Fe XIV] emission corona during the total eclipse of the Sun of 2008 August 1, in Mongolia (Altaj region) and i…

Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae

Taichi Kato, Akira Imada, Makoto Uemura +60

We systematically surveyed period variations of superhumps in SU UMa-type dwarf novae based on newly obtained data and past publications. In many systems, the evolution of superhum…

Photometry of Three Superoutbursts of the SU UMa-type Dwarf Nova, SW Ursae Majoris

Yuichi Soejima, Daisaku Nogami, Taichi Kato +16

We investigated the superhump evolution, analysing optical photometric observations of the 2000 February-March, the 2002 October-November, and the 2006 September superoutbursts of…

The nature of the light variability of the silicon star HR 7224

J. Krticka, Z. Mikulasek, G. W. Henry +4

Although photometric variations of chemically peculiar (CP) stars are frequently used to determine their rotational periods, the detailed mechanism of their light variability remai…

SDSS J080434.20+510349.2: Eclipsing WZ Sge-Type Dwarf Nova with Multiple Rebrightenings

Taichi Kato, Elena P. Pavlenko, Hiroyuki Maehara +8

We observed the 2006 superoutburst of SDSS J080434.20+510349.2 during its plateau phase, rebrightening phase, and post-superoutburst final decline. We found that this object is a g…

SN 2008S: an electron capture SN from a super-AGB progenitor?

M. T. Botticella, A. Pastorello, S. J. Smartt +31

We present comprehensive photometric and spectroscopic observations of the faint transient SN 2008S discovered in NGC 6946. SN 2008S exhibited slow photometric evolution and almost…

Relative photometry of transiting exoplanet CoRoT-Exo-2b

Peter Vereš, Ján Budaj, Jozef Világi +2

Relative CCD photometry of the extrasolar planet COROT-Exo-2b transiting in front of its parent star was carried out at the Astronomical and Geophysical Observatory of Comenius Uni…
