Understanding the origin of white dwarf atmospheric pollution by dynamical simulations based on detected three-planet systems
R. F. Maldonado, E. Villaver, A. J. Mustill +2
Between 25-50 % of white dwarfs (WD) present atmospheric pollution by metals, mainly by rocky material, which has been detected as gas/dust discs, or in the form of photometric tra…
ALMA's view of the Sun's nearest neighbours: The submm/mm SEDs of the alpha Centauri binary and a new source
R. Liseau, V. De la Luz, E. O'Gorman +3
The precise mechanisms that provide the non-radiative energy for heating the chromosphere and the corona of the Sun and other stars are at the focus of intense contemporary researc…
A new submm source within a few arcseconds of Centauri: ALMA discovers the most distant object of the solar system
R. Liseau, W. Vlemmings, E. O'Gorman +3
We recently announced the detection of an unknown submillimeter source in our ALMA observations of alpha Cen AB. The source was detected in two epochs, a strong detection at 445~GH…
Snapshot metallicity estimate of resolved stellar systems through Lick Fe5270 diagnostic
Alberto Buzzoni, Emanuele Bertone, Miguel Chavez
We outline a new method to derive a "snapshot" metallicity estimate of stellar systems (providing one resolves at least the brightest part of the CMD) just on the basis of low-reso…
Multiwavelenght analysis of Gl 355 (LQ Hya)
S. Covino, G. Tagliaferri, E. Bertone +8
We discuss ROSAT, ASCA, {\it Beppo}SAX and optical observations of the young active star Gl 355. During the ROSAT observation a strong flare was detected with a peak flux more than…
A Grid of Synthetic Stellar UV Fluxes
Lino H. Rodriguez-Merino, Miguel Chavez, Alberto Buzzoni +1
We present preliminary results of a large project aimed at creating an extended theoretical and observational database of stellar spectra in the ultraviolet wavelength range. This…
