Aims. We studied the thermal properties and chemical composition of the X-ray emitting plasma of a sample of bright members of the Taurus Molecular Cloud to investigate possible differences among classical and weak-lined T Tauri stars and possible dependences of the abundances on the stellar activity level and/or on the presence of accretion/circumstellar material. Methods. We used medium-resol...

This paper proposes a Bayesian account of asymmetries found in speech perception: In many languages, listeners show greater sensitivity if a non-coronal sound (/b/, /p/, /g/, /k/) is changed to coronal sounds (/d/, /t/) than vice versa. The currently predominant explanation for these asymmetries is that they reflect innate constraints from Universal Grammar. Alternatively, we propose that the a...

Abstract Coronal mass ejections (CMEs) – among the most energetic events originating from Sun can cause significant and sudden disruption to magnetic particulate environment of heliosphere. Thus, in current era space-based technologies, early warning that a CME has left is crucial. Some CMEs exhibit signatures at solar surface lower corona as eruption occurs, thus enabling their prediction befo...

Coronal magnetic flux ropes are generally considered to be the core structure of large-scale solar eruptions. Recent observations found that eruptions could initiated by a sequence "flux feeding," during which chromospheric fibrils rise upward from below, and merge with pre-existing prominence. Further theoretical study has confirmed feeding mechanism is efficient in causing eruption wrapped ba...

We present a system for the automatic retrieval of images with coronal loops from the solar image database captured by the SOHO/EIT satellite [1]. Our image retrieval system provides relevant data to astrophysicists who need such data to perform studies that shed light on the mysteries behind solar activities and to analyze the relations between coronal loops and other solar events. As part of ...
