Coronal jets represent important manifestations of ubiquitous solar transients, which may be the source of significant mass and energy input to the upper solar atmosphere and the solar wind. While the energy involved in a jet-like event is smaller than that of "nominal" solar flares and coronal mass ejections (CMEs), jets share many common

A small flare ribbon above a sunspot umbra in active region 12205 was observed on November 7, 2014, at 12:00 UT in the blue imaging channel of the 1.5 m GREGOR telescope, using a 1 Å Ca ii H interference filter. Context observations from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO), the Solar Optical Telescope

La búsqueda de exotierras por medio de espectroscopía doppler se enfrenta hoy en día a dos grandes dificultades. La primera es de carácter técnico. En estrellas de tipo solar la precisión de los instrumentos existentes limita la amplitud de las señales que se pueden medir a aquellas producidas por supertierras a separaciones orbitales cercanas a

Using kinematic maps from the Sloan Digital Sky Survey (SDSS) Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we reveal that the majority of low-mass quenched galaxies exhibit coherent rotation in their stellar kinematics. Our sample includes all 39 quenched low-mass galaxies observed in the first year of MaNGA. The galaxies are

An essential difference between the western and eastern provinces of the Roman Empire is the fact that sophisticated urban cultures had developed in Asia Minor and the Levant centuries before the Romans arrived. Underlying the Hellenized, and later Roman, veneer was a myriad of older local traditions and languages, which had an immense impact upon

Stars similar to the Sun, known as solar analogues, provide an excellent opportunity to study the preceding and following evolutionary phases of our host star. The unprecedented quality of photometric data collected by the Kepler NASA mission allows us to characterise solar-like stars through asteroseismology and study diagnostics of stellar
