CaII Kgrains, i.e., intermittent, short-lived (about 1 minute), periodic (2-4 minutes), pointlike chromospheric brightenings, are considered to be the manifestations of acoustic waves propagating upward from the solar surface and developing into shocks in the chromosphere. After the simulations of Carlsson and Stein, we know that hot shocked gas moving upward interacting with the downflowing chromospheric gas (falling down after having been displaced upward by a previous shock) nicely reproduces the spectral features of the CaII K profiles observed in such grains, i.e., a narrowband emissionAdvertised on

The XXXIV Canary Islands Winter School of Astrophysics closed last Thursday, November 16, with the visit to the facilities of the Obervatorio del Teide. For two weeks, 54 graduate students from 15 countries attended the IACTEC building to learn about the latest developments in the field of galaxy evolution and the Local Group. Currently, astrophysics field is receiving a big amount of data available for research due to the Gaia Mission and several spectroscopic surveys from Earth in which the IAC has a large participation. The organization highlights the great enthusiasm, the good atmosphereAdvertised on
