Solar prominences embedded in flux ropes: morphological features and dynamics from 3D MHD simulations
J. Terradas, R. Soler, M. Luna +3
The temporal evolution of a solar prominence inserted in a three-dimensional magnetic flux rope is investigated numerically. Using the model of Titov Demoulin (1999) under the regi…
Coherent response of a stochastic nonlinear oscillator to a driving force: analytical characterization of the spectral signatures
J. Plata
We study the dynamics of a classical nonlinear oscillator subject to noise and driven by a sinusoidal force. In particular, we give an analytical identification of the mechanisms r…
Molecular gas in low-metallicity starburst galaxies: Scaling relations and the CO-to-H conversion factor
Ricardo Amorín, C. Muñoz-Tuñón, J. A. L. Aguerri +1
We study the molecular content and the star formation efficiency of 21 Blue Compact Dwarfs (BCDs). We present CO(1-0) and (2-1) observations, further supplemented with additional C…
Constraining the properties of neutron star crusts with the transient low-mass X-ray binary Aql X-1
A. C. Waterhouse, N. Degenaar, R. Wijnands +4
Aql X-1 is a prolific transient neutron star low-mass X-ray binary that exhibits an accretion outburst approximately once every year. Whether the thermal X-rays detected in interve…
The JCMT Nearby Galaxies Legacy Survey X. Environmental Effects on the Molecular Gas and Star Formation Properties of Spiral Galaxies
Angus Mok, C. D. Wilson, J. Golding +9
We present a study of the molecular gas properties in a sample of 98 HI - flux selected spiral galaxies within Mpc, using the CO line observed with the James Clerk…
The Fe/Ni ratio in ionized nebulae: clues on dust depletion patterns
Gloria Delgado-Inglada, Adal Mesa-Delgado, Jorge García-Rojas +2
We perform a homogeneous analysis of the Fe/Ni abundance ratio in eight Galactic planetary nebulae (PNe) and three Galactic H II regions that include the Orion nebula, where we stu…
