We model in detail a flare observed on Proxima Centauri with the EPIC-PN on board XMM-Newton at high statistics and high time resolution and coverage. Time-dependent hydrodynamic loop modeling is used to describe the rise and peak of the light curve, and a large fraction of the decay, including its change of slope and a secondary maximum, over more than 2 h. The light curve, the emission measure and the temperature derived from the data allow us to constrain the loop morphology and the heating… 
Flares from small to large: X-ray spectroscopy of Proxima Centauri with XMM-Newton
We report results from a comprehensive study of the nearby M dwarf Proxima Centauri with the XMM-Newton satellite, using simultaneously its X-ray detectors and the Optical Monitor with its U band
Simultaneous optical and X-ray observations of a giant flare on the ultracool dwarf LP 412-31
Cool stars are known to produce flares probably as a result of the magnetic reconnection in their outer atmospheres. We present simultaneous XMM-Newton optical V band and X-ray observations of the M8
X-ray flares on the UV Ceti-type star CC Eridani: a ``peculiar'' time-evolution of spectral parameters
Context. Weak flares are supposed to be an important heating agent of th e outer layers of stellar atmospheres. However, due to instrumental limitations, only large X-ray flares have been studied in
Doppler imaging an X-ray flare on the ultrafast rotator BO Mic - A contemporaneous multiwavelength
We present an analysis of contemporaneous photospheric, chromospheric and coronal structures on the highly active K-dwarf star BO Mic (Speedy Mic). We concentrate on a moderate flare that we localize
X-Ray Flaring on the dMe Star, Ross 154
We present results from two Chandra imaging observations of Ross 154, a nearby flaring M dwarf star. During a 61 ks ACIS-S exposure, a very large flare occurred (the equivalent of a solar X3400
Multi-wavelength observations of Proxima Centauri
Aims. We report simultaneous observations of the nearby flare star Proxima Centauri with VLT/UVES and XMM-Newton over three nights in March 2009. Our optical and X-ray observations cover the star’s
Bright X-Ray Flares in Orion Young Stars from COUP: Evidence for Star-Disk Magnetic Fields?
We have analyzed a number of intense X-ray flares observed in the Chandra Orion Ultradeep Project (COUP), a 13 day observation of the Orion Nebula Cluster (ONC), concentrating on the events with the
XMM-Newton observation of the young open cluster Blanco 1. II. X-ray time variability and flares
We study the X-ray variability of the young open cluster Blanco 1 observed with the EPIC camera on board the XMM-Newton X-ray observatory. The time coverage of EPIC observations has allowed us to
X-RAY FLARES OF EV Lac: STATISTICS, SPECTRA, AND DIAGNOSTICS
We study the spectral and temporal behavior of X-ray flares from the active M dwarf EV Lac in 200 ks of exposure with the Chandra/HETGS. We derive flare parameters by fitting an empirical function

Hydrodynamic modeling of an X-ray flare on Proxima Centauri observed by the Einstein telescope
Hydrodynamic numerical calculations of a flare which occurred on Proxima Centauri and was observed by the Einstein satellite on August 20, 1980 at 12:50 UT are presented. The highlights of the
Pseudo-Two-dimensional Hydrodynamic Modeling of Solar Flare Loops
We have developed a "pseudo-two-dimensional" model of solar flare loops from one-dimensional hydrodynamic calculations. The model consists of thermally isolated and fixed semicircular loops with
X-Ray Evidence for Flare Density Variations and Continual Chromospheric Evaporation in Proxima Centauri
Using the XMM-Newton X-ray observatory to monitor the nearest star to the Sun, Proxima Centauri, we recorded the weakest X-ray flares on a magnetically active star ever observed. Correlated X-ray and
Modeling the Cooling of Postflare Loops
We present a model for the cooling of postflare loops. In our model, we form an arcade that consists of hundreds of loops with offset formation times to simulate a rising reconnection site. An

Numerical Simulations of Loops Heated to Solar Flare Temperatures - Part Two - X-Ray and Ultraviolet Spectroscopy
In the first paper in this series, numerical simulation techniques were used to investigate the fluid dynamics of plasma that is confined to a magnetic flux tube and is heated to solar flare
Continuous heating of a giant X-ray flare on Algol
Giant stellar flares can release large amounts of energy within a few days: X-ray emission alone can be up to ten per cent of the star's bolometric luminosity. These flares exceed the luminosities of

A survey of soft X-ray limb flare images obtained by the S-054 experiment on board Skylab is presented. From a morphological point of view, limb flares have been subdivided into three groups: (A)

A dynamical model is proposed for the formation of soft X-ray emitting hot loops in solar flares. It is examined by numerical simulations how a solar model atmosphere in a magnetic loop changes its
