Cataclysmic variables as possible counterparts of ancient Far Eastern guest stars

May 2020

Continuing our efforts to select possible classical nova candidates among Far Eastern guest stars and to identify them with modern cataclysmic variables (CVs), we present a search for counterparts in 24 promising areas of the sky corresponding to ancient observations between 204 BCE and 1690 CE. These areas have been derived by us in a previous paper. Based on physical entities of the CVs in our ... [Show full abstract] areas and reasonable magnitude limits compatible with the distribution of known eruption amplitudes of telescopic classical novae, we present a catalogue of a total of 80 CVs and related targets which could possibly have caused the historical sightings. This list could potentially be reduced by additionally discussing further information more vaguely given in the text. In some cases, we present a detailed discussion of the interpretation of ancient sources confronting them with properties of the brightest CVs in the field. In order to estimate whether this list is representative, we discuss the distribution of CV types in our catalogue of counterparts for the historical events. Compared to the entire sky, the surface density of most CV subtypes in our search fields reveals similar values, except for polars and intermediate polars, i. e. strongly magnetic CVs, for which a significant excess in our search fields was detected. Finally, we give an outlook towards future research in this topic, and add in an Appendix a complete atlas of the celestial maps of all 24 guest star events, displaying the search areas and locations of CVs within them.

The Sienese polymath Alessandro Piccolomini (1508-1579) was one of the leading proponents of his day for the making the natural sciences available to the lay reader in the vernacular. His earliest attempt is comprised of two works: De la Sfera del Mondo and De le Stelle Fisse, both of which were first printed in Venice in 1540. To date, neither volume has received more than cursory scholarly ... [Show full abstract] attention. The current study examines the scientific content of these two works, in particular that of De le Stelle Fisse because this book is on the one hand applauded as the first printed star atlas and on the other hand criticized for not meeting cartographic standards of those days. No attention has been paid to the actual purpose for which these maps were designed, namely as part of a method for teaching the constellations and their stars by observation at night instead of by book learning, maps or globes.

W. Tirion

The oldest star maps show us in the first place the artistic representation of the old traditional and mythological constellation figures. A modern sky atlas shows dots and symbols, representing stars and objects. In the 20th century many photographic star atlases have been made, some very expensive, others within the reach of most amateur astronomers. But a demand for hand-drawn atlases remains. ...

With the advent of the computer and the availability of fantastically accurate planetarium programs, the printed atlas has largely been replaced these days. For those who enjoy the printed article, or need something convenient for use at the telescope, the following are recommended. Many of the larger format maps are now out of print, so are now becoming harder to find.
