TL;DR: Hinode observations of chromospheric anemone jets suggest that magnetic reconnection similar to that in the corona is occurring at a much smaller spatial scale throughout the chromosphere, and suggest that the heating of the solar chromosphere and corona may be related to small-scale ubiquitous reconnection.

Molecular Loops in the Galactic Center: Evidence for Magnetic Flotation
Yasuo Fukui,Hiroaki Yamamoto,Motosuji Fujishita,Natsuko Kudo,Kazufumi Torii,Satoshi Nozawa,Kunio T. Takahashi,Ryoji Matsumoto,Mami Machida,Akiko Kawamura,Yoshinori Yonekura,Norikazu Mizuno,Toshikazu Onishi,Akira Mizuno +13 more
TL;DR: A magnetic flotation model is presented to explain that the formation of the loops is due to magnetic buoyancy caused by the Parker instability and has the potential to offer a coherent explanation for the origin of the violent motion and extensive heating of the molecular gas in the galactic center.
Journal ArticleDOI
Generation of Alfven Waves by Magnetic Reconnection
TL;DR: In this article, results of 2.5-dimensional magnetohydrodynamical simulations are reported for the magnetic reconnection of non-perfectly antiparallel magnetic fields, where the initial distribution of the plasma is assumed to be simple; density and pressure are uniform except for the current sheet region.
Journal Article
Magnetic Reconnection Associated with Emerging Magnetic Flux
TL;DR: In this paper, two-dimensional MHD numerical simulations have been performed in order to study magnetic reconnection between an emerging flux and an overlying coronal magnetic field, while taking into account the effect of gravity, high spatial resolution, and a sufficient time span.
Journal ArticleDOI

TL;DR: In this article, a survey of the molecular clouds in the Galaxy with the NANTEN mm telescope has discovered molecular loops in the galactic center region, which can be explained in terms of a buoyant rise of magnetic loops due to a Parker instability.
