A statistical study of spectral images, taken from the CRISP instrument at the Swedish 1-m Solar Telescope in H-alpha 656.28 nm of fast spicules, present Doppler velocities in the range of -41km/s to +41 km/s. Remarkably, many ... more
Author: Jae-Rim KooOscillating Algol-type eclipsing binaries (oEA) are very interesting objects that have three observational features of eclipse, pulsation, and mass transfer. Direct measurement of their masses and radii from the double-lined radia ... more
Author: Isabel ColmanWe present an analysis of 93 oscillating red giants from NASA's Kepler mission which exhibit anomalous single-frequency peaks in their amplitude spectra. These peaks may be indicative of binary star systems, with frequencies such ... more

Author: Orlagh CreeveyWe present stellar properties of 58 stars from a seismic inference using full-length data sets from Kepler (mass, age, radius, distances). These stars comprise active stars, planet-hosts, solar-analogs, and binary systems. By empl ... more
Author: Saskia HekkerFrom its surface proper.es it can be difficult to determine whether a red-giant star is in its Helium-core-burning phase or only burning Hydrogen in a shell around an inert Helium core. Stars in either of these stage can have simi ... more
Author: mutlu yildizSolar-like oscillation frequencies of 93 target stars of Kepler and CoRoT are analyzed. In the present study, we present results for two of them. Recently, two new reference frequencies nu_min1 and nu_min2 are found in the spacin ... more
Author: Mag. Erich HartigThe NASA Kepler K2 mission offers new opportunities to search for long period variables (LPVs) along the ecliptic plane.
We present first results of our observing proposals for ‘Super-Red-Targets’ in the Kepler K2 Campaigns ... more
Author: Ian RoxburghThe differences between the oscillation frequencies and uncertainty estimates of a star derived by different fitters can be large, sufficiently large so that, were one to find a stellar model that fitted one frequency set ($\chi^ ... more
Author: Mariachiara FalcoOne of the most visible manifestations of convective motions occurring in
the uppermost layers of the solar convection zone is the granulation. Strong
magnetic fields hinder the convective motions, but the appearance of bright
