An overshoot solar dynamo with a strong return meridional flow
Alfio Bonanno
The meridional circulation plays an essential role in determining the basic mechanism of the dynamo action in case the of a low eddy diffusivity. Flux-transport dynamos with strong…
Dynamical System Analysis of Cosmologies with Running Cosmological Constant from Quantum Einstein Gravity
Alfio Bonanno, Sante Carloni
We discuss a mechanism that induces a time-dependent vacuum energy on cosmological scales. It is based on the instability induced renormalization triggered by the low energy quantu…
Abundances in HD27411 and the helium problem in Am stars
G. Catanzaro, L. A. Balona
We analyze a high-resolution spectrum of the A3m star HD27411. We compare abundances derived from ATLAS9 model atmospheres with those using the more computationally-intensive ATLAS…
Na-O anticorrelation and HB. IX. Kinematics of the program clusters. A link between systemic rotation and HB morphology?
M. Bellazzini, A. Bragaglia, E. Carretta +4
We use accurate radial velocities for 1981 member stars in 20 Galactic globular clusters, collected within our large survey aimed at the analysis of the Na-O anti-correlation, to s…
Solar low-lying cool loops and their contribution to the transition region EUV output
C. Sasso, V. Andretta, D. Spadaro +1
In the last 30 years, the existence of small and cool magnetic loops (height < 8 Mm, T < 10^5 K) has been proposed and debated to explain the increase of the DEM (differential emis…
Constraining the physical properties of Type II-P supernovae using nebular phase spectra
Kate Maguire, Anders Jerkstrand, Stephen J. Smartt +6
We present a study of the nebular phase spectra of a sample of Type II-Plateau supernovae with identified progenitors or restrictive limits. The evolution of line fluxes, shapes, a…
