Flux Emergence from the Solar Interior to the Atmosphere: the Passage through the Photosphere
The atmosphere of the Sun is being stirred and reshaped continuously through the emergence of magnetized plasma from the convection zone. Magnetic elements...
Flux Emergence In The Solar Photosphere - Diagnostics Based On 3-D Rradiation-MHD Simulations
We investigate flux tube emergence in the solar photosphere using a diagnostic procedure based on analyzing Stokes signals from different spectral lines...
Follow up observationes of extremely metal-poor stars identified from SDSS and LAMOST
The most metal-poor stars in the Milky Way witnessed the early phases of formation of the Galaxy, and have chemical compositions close to the pristine mixture...
Follow-up observations of GLIMPSE selected Post-AGB candidates
We propose to use the last Spitzer observing cycle to increase the sample of hidden post-AGB stars with mid-infrared spectroscopy. We selected predominantly...
Follow-Up of Comet-Asteroid Transition Object 107P Wilson-Harrington During Its 2009 Return to Perihelium
We have been monitoring 107P comet-asteroid transition object during its 2009 return to perihelium. We have been unable of identifying any trace of cometary...
Footprints of the early Universe in the SFHs of dwarf galaxies
We present the star formation histories (SFHs) as a function of galactocentric radius of four isolated dwarf galaxies, Cetus, Tucana, LGS-3, and Phoenix. Our...
Forecasting precipitable water vapour at the Roque de los Muchachos Observatory
Modern optical and infrared astronomical sites are getting used to a flexible way of operation, namely queue modes, allowing astronomical observations in the...
