Super-elastic Collision of Large-scale Magnetized Plasmoids in The Heliosphere
Chenglong Shen, Yuming Wang, Shui Wang +7
Super-elastic collision is an abnormal collisional process, in which some particular mechanisms cause the kinetic energy of the system increasing. Most studies in this aspect focus…
Hot Ammonia around Young O-type Stars. II. JVLA imaging of highly-excited metastable ammonia masers in W51-North
Ciriaco Goddi, Christian Henkel, Qizhou Zhang +2
We have used the JVLA at the 1 cm band to map five highly-excited metastable inversion transitions of ammonia, (J,K)=(6,6), (7,7), (9,9), (10,10), and (13,13), in W51 IRS2 with ~0.…
Comment on "Detection and characterization of 0.5-8 MeV neutrons near Mercury: Evidence for a solar origin"
Gerald Share, Ronald Murphy, Allan Tylka +2
We argue that the hour-long neutron transient detected by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) Neutron Spectrometer beginning at 15:45 UT o…
NIR Spectroscopy of the HAeBe Star HD 100546: III. Further Evidence of an Orbiting Companion?
Sean D. Brittain, John S. Carr, Joan R. Najita +2
We report high resolution NIR spectroscopy of CO and OH emission from the Herbig Be star HD100546. We discuss how our results bear striking resemblance to several theoretically pre…
The impact of a filament eruption on nearby high-lying cool loops
L. K. Harra, S. A. Matthews, D. M. Long +2
The first spectroscopic observations of cool Mg II loops above the solar limb observed by NASA's Interface Region Imaging Spectrograph ({\it IRIS}; \cite{IRIS}) are presented. Duri…
Self-similar expansion of solar coronal mass ejections: implications for Lorentz self-force driving
Prasad Subramanian, K. P. Arunbabu, Angelos Vourlidas +1
We examine the propagation of several CMEs with well-observed flux rope signatures in the field of view of the SECCHI coronagraphs aboard the STEREO satellites using the GCS fittin…
