Simultaneous Observation of a Flux Rope Eruption and Magnetic Reconnection during an X-class Solar Flare [PDF]

open access: yes, 2018
In this Letter, we present a spectacular eruptive flare (X8.2) associated with a coronal mass ejection on 2017 September 10 at the west limb of the Sun.

A FLARE IN THE JET OF PICTOR A [PDF]

open access: yesThe Astrophysical Journal, 2010
A Chandra X-ray imaging observation of the jet in Pictor A showed a feature that appears to be a flare that faded between 2000 and 2002. The feature was not detected in a follow-up observation in 2009. The jet itself is over 150 kpc long and a kpc wide, so finding year-long variability is surprising.

Evidence for Partial Taylor Relaxation from Changes in Magnetic Geometry and Energy during a Solar Flare [PDF]

open access: yes, 2012
Solar flares are powered by energy stored in the coronal magnetic field, a portion of which is released when the field reconfigures into a lower energy state. Investigation of sunspot magnetic field topology during flare activity is useful to improve our

A Very Young Adult Female Patient with Hepatitis B Flare: A Case Report

open access: yesActa Medica Indonesiana, 2023
Hepatitis B virus (HBV) infection is a major global health problem. It can cause chronic infection and put people at high risk of death from cirrhosis and liver cancer.

Solar Flares [PDF]

open access: yesInternational Astronomical Union Colloquium, 1995
AbstractThere are many types of solar flare, but the classic type is a two-ribbon flare with three phases — a preflare phase, a rise phase and a main phase. The properties of these phases are described, together with some recent observational advances in understanding the conditions for solar flares.

Pseudoprogression after advanced first-line endocrine therapy in metastatic breast cancer with bone metastasis: A case report

open access: yesFrontiers in Oncology, 2023
Approximately 75% of patients with advanced breast cancer develop bone metastasis, which significantly affects both the quality of life and the survival rate of patients. Accurate determination of the status of bone metastases is important for developing

Deep Learning Based Solar Flare Forecasting Model. I. Results for Line-of-sight Magnetograms

open access: yes, 2018
Solar flares originate from the release of the energy stored in the magnetic field of solar active regions, the triggering mechanism for these flares, however, remains unknown.

Flares and the chromosphere [PDF]

open access: yesEarth, Planets and Space, 2009
Abstract The chromosphere (the link between the photosphere and the corona) plays a crucial role in flare and CME development. In analogies between flares and magnetic substorms, it is normally identified with the ionosphere, but we argue that the correspondence is not exact. Much of the important physics of this interesting region remains to

A Technique for Automated Determination of Flare-ribbon Separation and Energy Release

open access: yes, 2009
We present a technique for automatic determination of flare-ribbon separation and the energy released during the course of two-ribbon flares. We have used chromospheric H$\alpha$ filtergrams and photospheric line-of-sight magnetograms to analyse flare ...
