Abstract Coronal mass ejections (CMEs) are explosive events that occur basically daily on the Sun. It is thought that these events play a crucial role in the angular momentum and mass loss of late-type stars, and also shape the environment in which planets form and live. Stellar CMEs can be detected in optical spectra in the Balmer lines, especially in Hα, as blue-shifted extra emission/absorption. To increase the detection probability one can monitor young open clusters, in which the stars are… 
Stellar coronal mass ejections – I. Estimating occurrence frequencies and mass-loss rates
Stellar coronal mass ejections (CMEs) may play an important role in mass- and angular momentum loss of young Sun-like stars. If occurring frequently, they may also have a strong effect on planetary
A census of coronal mass ejections on solar-like stars
Coronal mass ejections (CMEs) may have major importance for planetary and stellar evolution. Stellar CME parameters, such as mass and velocity, have yet not been determined statistically. So far
Mass Loss Rates from Coronal Mass Ejections: A Predictive Theoretical Model for Solar-Type Stars
Coronal mass ejections (CMEs) are eruptive events that cause a solar-type star to shed mass and magnetic flux. CMEs tend to occur together with flares, radio storms, and bursts of energetic
Probable detection of an eruptive filament from a superflare on a solar-type star
Solar flares are often accompanied by filament/prominence eruptions (~10 4  K and ~10 10−11  cm −3 ), sometimes leading to coronal mass ejections that directly affect the Earth’s environment 1 , 2 .
Slingshot prominences: coronal structure, mass loss and spin down
The structure of a star’s coronal magnetic field is a fundamental property that governs the high-energy emission from the hot coronal gas and the loss of mass and angular momentum in the stellar
Slingshot prominences: a hidden mass loss mechanism
Whilst ‘slingshot’ prominences have been observed on M-dwarfs, most if not all theoretical studies have focused on solar-like stars. We present an investigation into stellar prominences around
The flare-activity of 2MASS J16111534–1757214 in the upper Scorpius association
Flares are known to play an important role for the evolution of the atmospheres of young planets. In order to understand the evolution of planets, it is thus important to study the flare-activity


A search for flares and mass ejections on young late-type stars in the open cluster Blanco-1
We present a search for stellar activity (flares and mass ejections) in a sample of 28 stars in the young open cluster Blanco-1. We use optical spectra obtained with ESO's VIMOS multi-object
Connecting Flares and Transient Mass Loss Events in Magnetically Active Stars
We explore the ramification of associating the energetics of extreme mag- netic reconnection events with transient mass loss in a stellar analogy with solar eruptive events. We establish energy
Search for indications of stellar mass ejections using FUV spectra
Aims. We search for highly energetic activity phenomena in a small sample of late-type main-sequence stars in the far ultraviolet (FUV) using data from the Far Ultraviolet Spectroscopic Explorer
Stellar flares and the dark energy of CMEs
Abstract Flares we observe on stars in white light, UV or soft X-rays are probably harbingers of coronal mass ejections (CMEs). If we use the Sun as a guide, large stellar flares will dissipate two
Implications of mass and energy loss due to coronal mass ejections on magnetically-active stars
Analysis of a database of solar coronal mass ejections (CMEs) and associated flares over the period 1996-2007 finds well-behaved power law relationships between the 1-8 AA flare X-ray fluence and CME
We develop an empirical model to estimate mass-loss rates via coronal mass ejections (CMEs) for solar-type pre-main-sequence (PMS) stars. Our method estimates the CME mass-loss rate from the observed
Coronal mass ejection (CME) activity of low mass M stars as an important factor for the habitability of terrestrial exoplanets. II. CME-induced ion pick up of Earth-like exoplanets in close-in habitable zones.
It is suggested that larger and more massive terrestrial-type exoplanets may better protect their atmospheres against CMEs, because the larger cores of such exoplanet would generate stronger magnetic moments and their higher gravitational acceleration would constrain the expansion of their thermosphere-exosphere regions and reduce atmospheric escape.
Multiwavelength Signatures of Magnetic Activity from Young Stellar Objects in the LkHα 101 Cluster
We describe the results of our multiwavelength observing campaign on the young stellar objects in the LkHα 101 cluster. Our simultaneous X-ray and multifrequency radio observations are unique in
Investigating magnetic activity in very stable stellar magnetic fields: long-term photometric and spectroscopic study of the fully convective M4 dwarf V374 Peg
The ultrafast-rotating ($P_\mathrm{rot}\approx0.44 d$) fully convective single M4 dwarf V374 Peg is a well-known laboratory for studying intense stellar activity in a stable magnetic topology. As an
Different Power-law Indices in the Frequency Distributions of Flares with and without Coronal Mass Ejections
We investigated the frequency distributions of flares with and without coronal mass ejections (CMEs) as a function of flare parameters (peak flux, fluence, and duration of soft X-ray flares). We used
