The Measurement of Solar Diameter and Limb Darkening Function with the Eclipse Observations
Andrea Raponi, Costantino Sigismondi, Konrad Guhl +2
The Total Solar Irradiance varies over a solar cycle of 11 years and maybe over cycles with longer period. Is the solar diameter variable over time too? We introduce a new method t…
Measuring solar disk shape up to relativistic accuracy: the role of scintillation in ancient naked eye data
Costantino Sigismondi, Richard Nugent, Gerhard Dangl
The orbital displacement of the Moon is known to a precision on the order of centimeters from the lunar laser ranging data, while the lunar profile's confidence level is still only…
Towards a unified definition of solar limb during central eclipses and daily transits
Costantino Sigismondi, Andrea Raponi, Cyril Bazin +1
The diameter of the Sun has been measured using Baily's beads during central eclipses, observed with portable telescopes. A blend of tiny emission lines produced in the first sever…
