Nonlinear steepening of a fast magnetoacoustic wave in the vicinity of a coronal magnetic null point
Yu Zhong, Valery M. Nakariakov, Mariana Cécere +1
The interaction of a fast magnetoacoustic wave with a magnetic null point is studied in the context of the sympathetic flare phenomenon. Attention is paid to steepening the wave ca…
New insight into the variability of the Be star Aquarii: Determination of stellar and disk parameters
D. Concha, C. Arcos, D. Turis-Gallo +4
The Be star Aquarii shows peculiar Cas-type X-ray emission, likely caused by its outer disk interacting with a low-mass companion, probably a white dwarf. We study the long…
A high-resolution radio study of the L1551 IRS 5 and L1551 NE jets
A. Feeney-Johansson, S. J. D. Purser, T. P. Ray +10
Using observations with e-MERLIN and the VLA, together with archival data from ALMA, we obtain high-resolution radio images of two binary YSOs: L1551 IRS 5 and L1551 NE, covering a…
Modulation depth of the gyrosynchrotron emission as identifier of fundamental sausage modes
M. Cécere, A. Costa, T. Van Doorsselaere
We study the intensity, the modulation depth and the mean modulation depth of the gyrosynchrotron (GS) radiation as a function of the frequency and the line of sight (LOS) in fast…
Understanding the deflection of the `Cartwheel CME': data analysis and modeling
Abril Sahade, Angelos Vourildas, Laura Balmaceda +1
We study the low corona evolution of the `Cartwheel' coronal mass ejection (CME; 2008-04-09) by reconstructing its 3D path and modeling it with magneto-hydrodynamic simulations. Th…
Monitoring of the polarized maser emission around the massive protostars W75N(B)-VLA1 and W75N(B)-VLA2
G. Surcis, W. H. T. Vlemmings, C. Goddi +8
Several radio sources have been detected in the HMSFR W75N(B), among them the massive YSOs VLA1 and VLA2 are of great interest. These are thought to be in different evolutionary st…
