Margherita Hack's Astrophysics at the Asiago Astrophysical Observatory
G. Umbriaco, A. Bianchini, A. Pizzella +6
Margherita Hack observed with the Galileo telescope at the Asiago Astrophysical Observatory from September 1951 to March 1954. Using the spectroscopic facilities of the observatory…
The planetary theory of solar activity variability: a review
Nicola Scafetta, Antonio Bianchini
Commenting the 11-year sunspot cycle, Wolf (1859, MNRAS 19, 85-86) conjectured that "the variations of spot frequency depend on the influences of Venus, Earth, Jupiter, and Saturn"…
Echoes of a Squeezed Oscillator
Roberto Merlin, Andrea Bianchini
Pulses applied to an inhomogeneously broadened set of harmonic oscillators, previously prepared in squeezed states, can lead to a recovery of coherence, manifesting itself as echoe…
CXO J004318.8+412016, a steady supersoft X-ray source in M 31
M. Orio, G. J. M. Luna, R. Kotulla +14
We obtained an optical spectrum of a star we identify as the optical counterpart of the M31 Chandra source CXO J004318.8+412016, because of prominent emission lines of the Balmer s…
On the astronomical origin of the Hallstatt oscillation found in radiocarbon and climate records throughout the Holocene
Nicola Scafetta, Franco Milani, Antonio Bianchini +1
An oscillation with a period of about 2100-2500 years, the Hallstatt cycle, is found in cosmogenic radioisotopes (C-14 and Be-10) and in paleoclimate records throughout the Holocen…
Chemical and physical parameters from X-ray high resolution spectra of the Galactic nova V959 Mon
U. Peretz, M. Orio, E. Behar +5
Two observations of V959 Mon, done using the Chandra X-ray gratings during the late outburst phases (2012 September and December), offer extraordinary insight into the physics and…
