Improved parameters for the transiting hot Jupiters WASP-4b and WASP-5b
M. Gillon, B. Smalley, L. Hebb +6
The gaseous giant planets WASP-4b and WASP-5b are transiting 12 magnitude solar-type stars in the Southern hemisphere. The aim of the present work is to refine the parameters of th…
WASP-12b: The hottest transiting planet yet discovered
L. Hebb, A. Collier-Cameron, B. Loeillet +15
We report on the discovery of WASP-12b, a new transiting extrasolar planet with and . The planet and host star propertie…
Diffuse ionized gas in spiral galaxies and the disk-halo interaction
R. J. Reynolds, L. M. Haffner, G. J. Madsen +2
Thick layers of warm, low density ionized hydrogen (i.e., the warm ionized medium or WIM) in spiral galaxies provide direct evidence for an interaction between the disk and halo. T…
Long term optical and X-ray variability of the Seyfert galaxy Markarian 79
E. Breedt, P. Arévalo, I. M. McHardy +8
We present the results of concurrent X-ray and optical monitoring of the Seyfert 1 galaxy Mrk 79 over a period of more than five years. We find that on short to medium time-scales…
Dynamic non-null magnetic reconnection in three dimensions - II. Composite solutions
A. L. Wilmot-Smith, G. Hornig, E. R. Priest
In this series of papers we examine magnetic reconnection in a domain where the magnetic field does not vanish and the non-ideal region is localised in space. In a previous paper w…
The influence of multiple stars on the high-mass stellar initial mass function and age-dating of young massive star clusters
C. Weidner, P. Kroupa, T. Maschberger
The study of young stellar populations has revealed that most stars are in binary or higher order multiple systems. In this study the influence on the stellar initial mass function…
An ecological approach to problems of Dark Energy, Dark Matter, MOND and Neutrinos
HongSheng Zhao
Modern astronomical data on galaxy and cosmological scales have revealed powerfully the existence of certain dark sectors of fundamental physics, i.e., existence of particles and f…
Activity and rotation of low mass stars in young open clusters
Andreas Seifahrt, Ansgar Reiners, Aleks Scholz +1
We present first results from a multi-object spectroscopy campaign in IC2602, the Hyades, the Pleiades, and the Coma cluster using VLT/FLAMES. We analysed the data for radial veloc…
Stellar mass ejections
M. Jardine, J. -F. Donati, S. G. Gregory
It has been known for some time now that rapidly-rotating solar-like stars possess the stellar equivalent of solar prominences. These may be three orders of magnitude more massive…
Magnetic coronae of active main-sequence stars
M. Jardine, J. -F. Donati
The coronal structure of main sequence stars continues to puzzle us. While the solar corona is relatively well understood, it has become clear that even stars of the same mass as t…
Eruption of magnetic flux ropes during flux emergence
V. Archontis, T. Torok
Aims: We investigate the formation of flux ropes in a flux emergence region and their rise into the outer atmosphere of the Sun. Methods: We perform 3D numerical experiments solvin…
Galaxy evolution by color-log(n) type since redshift unity in the Hubble Ultra Deep Field
Ewan Cameron, Simon P. Driver
We explore the use of the color-log(n) plane (where n is the global Sersic index) as a tool for subdividing the high redshift galaxy population in a physically-motivated manner. Us…
Magnetic activity in the photosphere of CoRoT-Exo-2a. Active longitudes and short-term spot cycle in a young Sun-like star
A. F. Lanza, I. Pagano, G. Leto +18
The space experiment CoRoT has recently detected transits by a hot Jupiter across the disc of an active G7V star (CoRoT-Exo-2a) that can be considered as a good proxy for the Sun a…
The Number Of Magnetic Null Points In The Quiet Sun Corona
D. W. Longcope, C. E. Parnell
The coronal magnetic field above a particular photospheric region will vanish at a certain number of points, called null points. These points can be found directly in a potential f…
The Monitor project: Rotation periods of low-mass stars in M50
Jonathan Irwin, Suzanne Aigrain, Jerome Bouvier +4
We report on the results of a time-series photometric survey of M50 (NGC 2323), a ~130 Myr open cluster, carried out using the CTIO 4m Blanco telescope and Mosaic-II detector as pa…
Welcome back, Polaris the Cepheid
H. Bruntt, A. J. Penny, D. Stello +2
For about 100 years the amplitude of the 4-day pulsation in Polaris has decreased. We present new results showing a significant increase in the amplitude based on 4.5 years of cont…
Planetary microlensing signals from the orbital motion of the source star around the common barycentre
S. Rahvar, M. Dominik
With several detections, the technique of gravitational microlensing has proven useful for studying planets that orbit stars at Galactic distances, and it can even be applied to de…
The relation between stellar mass and weak lensing signal around galaxies: Implications for MOND
Lanlan Tian, Henk Hoekstra, Hongsheng Zhao
We study the amplitude of the weak gravitational lensing signal as a function of stellar mass around a sample of relatively isolated galaxies. This selection of lenses simplifies t…
Star Formation Around Super-Massive Black Holes
I. A. Bonnell, W. K. M. Rice
The presence of young massive stars orbiting on eccentric rings within a few tenths of a parsec of the supermassive black hole in the Galactic centre is challenging for theories of…
Rotational Line Emission from Water in Protoplanetary Disks
R. Meijerink, D. R. Poelman, M. Spaans +2
Circumstellar disks provide the material reservoir for the growth of young stars and for planet formation. We combine a high-level radiative transfer program with a thermal-chemica…
Stellar spindown: From the ONC to the Sun
Alexander Scholz
Rotation is a key parameter in the evolution of stars. From 1 Myr (the age of the ONC) to 4.5 Gyr (the age of the Sun), solar-like stars lose about 1-2 orders of specific angular m…
The structure and dynamics of a bright point as seen with Hinode, SoHO and TRACE
D. Pérez-Suárez, R. C. Maclean, J. G. Doyle +1
Our aim is to determine the plasma properties of a coronal bright point and compare its magnetic topology extrapolated from magnetogram data with its appearance in X-ray images. We…
