Systematic non-thermal velocity increase preceding soft X-ray flare onset: A large-scale Hinode/EIS study
Andy S. H. To, Abigail Burden, Deborah Baker +12
Non-thermal velocities, derived from spectral line broadening, can provide crucial insights into plasma dynamics before and during solar flares. To systematically study the pre-fla…
On the million-degree signature of spicules
Souvik Bose, Jayant Joshi, Paola Testa +1
Spicules have often been proposed as substantial contributors toward the mass and energy balance of the solar corona. While their transition region (TR) counterpart has unequivocal…
On the Nature of Nonthermal Broadening of Spectral Lines Observed by IRIS
Kyuhyoun Cho, Bart De Pontieu, Paola Testa
The origin of nonthermal broadening in solar spectra is one of the long-standing questions in solar physics. Various processes have been invoked - including unresolved flows, waves…
The Nature of X-Rays from Young Stellar Objects in the Orion Nebula Cluster -- A Chandra HETGS Legacy Project
Norbert S. Schulz, David P. Huenemoerder, David A. Principe +10
The Orion Nebula Cluster (ONC) is the closest site of very young ( 1 Myrs) massive star formation. The ONC hosts more than 1600 young and X-ray bright stars with masses rangi…
Bright hot impacts by erupted fragments falling back on the Sun: magnetic channelling
A. Petralia, F. Reale, S. Orlando +1
Dense plasma fragments were observed to fall back on the solar surface by the Solar Dynamics Observatory after an eruption on 7 June 2011, producing strong EUV brightenings. Previo…
Bright hot impacts by erupted fragments falling back on the Sun: UV redshifts in stellar accretion
F. Reale, S. Orlando, P. Testa +2
A solar eruption after a flare on 7 Jun 2011 produced EUV-bright impacts of fallbacks far from the eruption site, observed with the Solar Dynamics Observatory. These impacts can be…
Testing magnetically confined wind shock models for Beta Cep using XMM-Newton and Chandra phase-resolved X-ray observations
F. Favata, C. Neiner, P. Testa +2
(abridged) We have performed a set of phase-resolved X-ray observations of the magnetic B star Beta Cep, for which theoretical models predict the presence of a confined wind emitti…
