Evolution of the electronic excitation spectrum with strongly diminishing hole-density in superconducting Bi_{2}Sr_{2}CaCu_{2}O_{8+δ}
J. W. Alldredge, Jinho Lee, K. McElroy +8
A complete knowledge of its excitation spectrum could greatly benefit efforts to understand the unusual form of superconductivity occurring in the lightly hole-doped copper-oxides.…
Models for the Formation of Massive Stars
Mark R. Krumholz, Ian A. Bonnell
The formation of massive stars is currently an unsolved problems in astrophysics. Understanding the formation of massive stars is essential because they dominate the luminous, kine…
MHD mode coupling in the neighbourhood of a 2D null point
J. A. McLaughlin, A. W. Hood
At this time there does not exist a robust set of rules connecting low and high waves across the layer. The work here contributes specifically to what happens when…
Neutrinos as galactic dark matter in the Ursa Major galaxy group?
G. Gentile, H. S. Zhao, B. Famaey
We present the analysis of 23 published rotation curves of disk galaxies belonging to the Ursa Major group of galaxies, with kinematics free of irregularities. The rotation curves…
MHD Wave Propagation in the Neighbourhood of Two Null Points
J. A. McLaughlin, A. W. Hood
The nature of fast magnetoacoustic and Alfvén waves is investigated in a zero plasma in the neighbourhood of a pair of two-dimensional null points. This gives an indication of…
MHD wave propagation in the neighbourhood of a two-dimensional null point
J. A. McLaughlin, A. W. Hood
The nature of fast magnetoacoustic and Alfvén waves is investigated in a zero plasma. This gives an indication of wave propagation in the low solar corona. It is found that…
Magnetohydrodynamics wave propagation in the neighbourhood of two dipoles
J. A. McLaughlin, A. W. Hood
This paper is the third in a series of investigations by the authors. The nature of fast magnetoacoustic and Alfvén waves is investigated in a 2D plasma in the neighbourhood…
3D MHD Coronal Oscillations About a Magnetic Null Point: Application of WKB Theory
J. A. McLaughlin, J. S. L. Ferguson, A. W. Hood
This paper is a demonstration of how the WKB approximation can be used to help solve the linearised 3D MHD equations. Using Charpit's Method and a Runge-Kutta numerical scheme, we…
Non-linear force-free field modeling of a solar active region around the time of a major flare and coronal mass ejection
C. J. Schrijver, M. L. DeRosa, T. Metcalf +14
Solar flares and coronal mass ejections are associated with rapid changes in field connectivity and powered by the partial dissipation of electrical currents in the solar atmospher…
The On/Off Nature of Star-Planet Interactions
Evgenya Shkolnik, David A. Bohlender, Gordon A. H. Walker +1
Evidence suggesting an observable magnetic interaction between a star and its hot Jupiter appears as a cyclic variation of stellar activity synchronized to the planet's orbit. In t…
Hölder-differentiability of Gibbs distribution functions
Marc Kesseböhmer, Bernd O. Stratmann
In this paper we give non-trivial applications of the thermodynamic formalism to the theory of distribution functions of Gibbs measures (devil's staircases) supported on limit sets…
Comparison of cloud models for Brown Dwarfs
Ch. Helling, A. Ackerman, F. Allard +8
A test case comparison is presented for different dust cloud model approaches applied in brown dwarfs and giant gas planets. We aim to achieve more transparency in evaluating the u…
Modelling the Global Solar Corona II: Coronal Evolution and Filament Chirality Comparison
A. R. Yeates, D. H. Mackay, A. A. van Ballegooijen
The hemispheric pattern of solar filaments is considered using newly-developed simulations of the real photospheric and 3D coronal magnetic fields over a 6-month period, on a globa…
SuperWASP-N Extra-solar Planet Candidates from Fields 06hr < RA < 16hr
S. R. Kane, W. I. Clarkson, R. G. West +21
The Wide Angle Search for Planets (WASP) survey currently operates two installations, designated SuperWASP-N and SuperWASP-S, located in the northern and southern hemispheres respe…
Dusty disks at the bottom of the IMF
Aleks Scholz, Ray Jayawardhana
'Isolated planetary mass objects' (IPMOs) have masses close to or below the Deuterium-burning mass limit (~15 Jupiter masses) -- at the bottom of the stellar initial mass function.…
The Monitor project: Rotation of low-mass stars in NGC 2362 -- testing the disc regulation paradigm at 5 Myr
Jonathan Irwin, Simon Hodgkin, Suzanne Aigrain +4
We report on the results of a time-series photometric survey of NGC 2362, carried out using the CTIO 4m Blanco telescope and Mosaic-II detector as part of the Monitor project. Rota…
The stable magnetic field of the fullly-convective star V374 Peg
J. Morin, J. -F. Donati, T. Forveille +10
We report in this paper phase-resolved spectropolarimetric observations of the rapidly-rotating fully-convective M4 dwarf V374 Peg, on which a strong, mainly axisymmetric, large-sc…
Oscillations in Procyon A: First results from a multi-site campaign
S. Hekker, T. Arentoft, H. Kjeldsen +45
Procyon A is a bright F5IV star in a binary system. Although the distance, mass and angular diameter of this star are all known with high precision, the exact evolutionary state is…
The Monitor project: Rotation of low-mass stars in the open cluster NGC 2547
Jonathan Irwin, Simon Hodgkin, Suzanne Aigrain +3

Fiber-optical analogue of the event horizon
Thomas G. Philbin, Chris Kuklewicz, Scott Robertson +3
The physics at the event horizon resembles the behavior of waves in moving media. Horizons are formed where the local speed of the medium exceeds the wave velocity. We use ultrasho…
Observation of negative-frequency waves in a water tank: A classical analogue to the Hawking effect?
Germain Rousseaux, Christian Mathis, Philippe Maissa +2
The conversion of positive-frequency waves into negative-frequency waves at the event horizon is the mechanism at the heart of the Hawking radiation of black holes. In black-hole a…
