Historical supernovae: Tuesday block 2
- Costantino Sigismondi (ICRA Sapienza and ICRANET Pescara)
Description
The last Supernova observed in our galaxy occurred five years before the invention of the telescope by Galileo. Nevertheless the accuracy achieved by Tycho Brahe in observational astronomy already surpassed the Chinese standards based on the comparison with some fixed stars' positions. The understanding of the intrinsic difference between Novae and Supernovae was possible only in the XX century, and the correlation of some Supernovae with GRB is a XXI century scientific task.
We would like to focus on the development of the astronomical knowledge marked with the historical galactic supernovae, and the most relevant extragalactic ones, up to the present.
Featuring:
- Naked eye astronomy along the history
- The Lupus' 1006 Supernova
- The Chinese 1054 progenitor of the Crab Nebula
- Tycho and the 1572 Supernova
- Galileo and Kepler's roles with the 1604 Supernova
- From S Andromedae to SN 1987 A
- Novae, Supernovae, Kilonovae and Hypernovae:an historical approach
To study the historical galactic Supernovae it is necessary the knowledge of the observations made with the naked eye. Within 2' of theoretical angular accuracy in daytime and 1' in nightime, the astronomical observations made before Tycho were conducted artistically, depending on the skills, the techniques available and the inspiration of the astronomers.
Galileo Galilei stands in between...
The particles ejected from the Sun during some particularly powerful eruptions (X-ray flare class X) reach the Earth in twenty minutes, immediately after the photons that carry the image and information of the event.
The speed of the most energetic protons of the solar wind is measurable from the images of C3 coronagraph of SOHO SOlar and Heliospheric Observatory and from the X-ray and proton...
A panorama of the current historiography on the Supernova of 1054 is outlined. Shklovsky (1968), and Murdin (1985) show how the interpretation of this phenomenon converged on a Su-pernova event. Here we reconsider the historical data, assuming a Gamma-Ray Burst (GRB) as its source. A Supernova correlated with the GRB explains well the fading time observed by the an-cient Chinese astronomers,...
