Using Solar Orbiter as an upstream solar wind monitor for real time space weather predictions
R. Laker, T. S. Horbury, H. O'Brien +11
Coronal mass ejections (CMEs) can create significant disruption to human activities and systems on Earth, much of which can be mitigated with prior warning of the upstream solar wi…
Virtual Observatory studies of Planetary Nebulae
R. P. Mignani, F. Kerber, R. L. Smart +5
Starting from the Strasbourg ESO Catalogue (SEC) of Planetary Nebulae (PNe), the largest PNe compilation available with ~ 1500 objects, we undertook a comprehensive study of the wh…
New constraints on GRB jet geometry and relativistic shock physics
C. Guidorzi, C. G. Mundell, R. Harrison +23
We use high--quality, multi-band observations of Swift GRB120404A, from gamma-ray to radio frequencies, together with the new hydrodynamics code of van Eerten et al. (2012) to test…
A numerical study of the Schrodinger-Newton equation 1: Perturbing the spherically-symmetric stationary states
R. Harrison, I. Moroz, K. P. Tod
We consider the linear stability of the spherically-symmetric stationary solutions of the Schrodinger-Newton equations. We find that the ground state is linearly stable, with only…
A numerical study of the Schrodinger-Newton equation 2: the time-dependent problem
R. Harrison, I. Moroz, K. P. Tod
We present a numerical study of the time-dependent SN equations in 3 dimensions with 3 different kinds of symmetry: spherically symmetric, axially symmetric and translationally sym…
Benchtop magnetic shielding for benchmarking atomic magnetometers
P. J. Hobson, N. Holmes, P. Patel +14
Here, a benchtop hybrid magnetic shield containing four mumetal cylinders and nine internal flexible printed circuit boards is designed, constructed, tested, and operated. The shie…
Magnetic Imaging of the Outer Solar Atmosphere (MImOSA): Unlocking the driver of the dynamics in the upper solar atmosphere
H. Peter, E. Alsina Ballester, V. Andretta +20
The magnetic activity of the Sun directly impacts the Earth and human life. Likewise, other stars will have an impact on the habitability of planets orbiting these host stars. The…
Arrival time calculation for interplanetary coronal mass ejections with circular fronts and application to STEREO observations of the 2009 February 13 eruption
C. Möstl, T. Rollett, N. Lugaz +11
A goal of the NASA STEREO mission is to study the feasibility of forecasting the direction, arrival time and internal structure of solar coronal mass ejections (CMEs) from a vantag…
Radio flares from gamma-ray bursts
D. Kopac, C. G. Mundell, S. Kobayashi +6
We present predictions of centimeter and millimeter radio emission from reverse shocks in the early afterglows of gamma-ray bursts with the goal of determining their detectability…
GRB 130427A: a Nearby Ordinary Monster
A. Maselli, A. Melandri, L. Nava +63
Long-duration Gamma-Ray Bursts (GRBs) are an extremely rare outcome of the collapse of massive stars, and are typically found in the distant Universe. Because of its intrinsic lumi…
Science Objectives for an X-Ray Microcalorimeter Observing the Sun
J. Martin Laming, J. Adams, D. Alexander +57
We present the science case for a broadband X-ray imager with high-resolution spectroscopy, including simulations of X-ray spectral diagnostics of both active regions and solar fla…
The Solar Orbiter SPICE instrument -- An extreme UV imaging spectrometer
The SPICE Consortium, :, M. Anderson +88
The Spectral Imaging of the Coronal Environment (SPICE) instrument is a high-resolution imaging spectrometer operating at extreme ultraviolet (EUV) wavelengths. In this paper, we p…
Phenomenology of Reverse-Shock Emission in the Optical Afterglows of Gamma Ray Bursts
J. Japelj, D. Kopac, S. Kobayashi +6
We use a parent sample of 118 gamma-ray burst (GRB) afterglows, with known redshift and host galaxy extinction, to separate afterglows with and without signatures of dominant rever…
GRB 091024A and the nature of ultra-long gamma-ray bursts
F. J. Virgili, C. G. Mundell, V. Pal'shin +30
We present a broadband study of gamma-ray burst (GRB) 091024A within the context of other ultra-long-duration GRBs. An unusually long burst detected by Konus-Wind, Swift, and Fermi…
