Poster

We report on ongoing projects related to observations of prominent Carbon stars in the L-band. This wavelength region is of particular interest as it covers a strong band of C$_2$H$_2$ a building block of Carbon dust. The instruments used are MATISSE at the VLT Interferometer and ALES at LBTI.

79. PARSEC V2.0: Stellar tracks and isochrones of low and intermediate mass stars with rotation

Poster

We present a new comprehensive collection of stellar evolutionary tracks and isochrones for rotating low- and intermediate-mass stars assembled with the updated version of PARSECV2.0. The recent calibration of the extra mixing from overshooting and rotation is included, as well as several improvements in nuclear reaction network, treatment of convective zones, mass loss and other physical...

Symbiotic stars are interacting binary systems consisting of a companion star, usually a white dwarf, and a primary star, usually a red giant. In general, there are two phases of symbiotic stars: accreting- only and burning-type. There are several hundred known symbiotic systems, most of which are in the burning phase, but that is due to an observational bias. In the burning-type case, we...

48. Upgrading the dppn45 post-processing nucleosynthesis code

Poster

Decay rates have a significant effect on the abundance of branching point elements and short-lived nuclei. Thus, a correct description of the decay rates is essential for the accurate study of the s-process in AGB stars. The dppns45 post-processing nucleosynthesis code calculates the changes in the abundances of isotopes due to mixing and nuclear burning after the detailed stellar structure...

64. The recent achievements of the RockStar Group of the Perugia University on astrophysical modeling and pallasite geochemistry.

Poster

Here, we summarize the first achievements of the RockStar Group of the Department of Physics and Geology (at the University of Perugia, Italy). The group was created on the initiative of Maurizio Busso and consists of a close collaboration between Physicists and Geologists on astrophysical and planetological studies. Astrophysical modeling takes significant advantage of geochemical...
