The Dog Stars: The hope-filled story of a world changed by global catastrophe

Product Information

Sirius B is 10,000 times less luminous, but a brighter X-ray source of the two. It orbits around the primary component in a wide horizontal ellipse when observed from Earth. The star has an estimated surface temperature of 25,200 K. It is the nearest known white dwarf.

Pull the Thread: Lots of little details lead Higs to realize just in time that something is very wrong as he is landing the Beast at the airport near the end of the novel.Maskelyne, N. (1759). "LXXVIII. A proposal for discovering the annual parallax of Sirius". Philosophical Transactions of the Royal Society. 51: 889–895. Bibcode: 1759RSPT...51..889M. doi: 10.1098/rstl.1759.0080. Since 1894, irregularities have been tentatively observed in the orbits of SiriusA and B with an apparent periodicity of 6–6.4years. A 1995 study concluded that such a companion likely exists, with a mass of roughly 0.05solar mass—a small red dwarf or large brown dwarf, with an apparent magnitude of more than 15, and less than 3 arcseconds from Sirius A.

For the Evulz: This appears to be the motive of the airport couple, Higs notes that they certainly weren't getting anything useful off their victims.After the End: Most of the population has died from a super flu. Many of the survivors of that are suffering from a blood disease.

Sirius is a binary star system consisting of two white stars orbiting each other with a separation of about 20AU [e]At the closest approach every 50 years, Sirius A and Sirius B can only be resolved with a 12-inch telescope in good viewing conditions. As the two stars approach each other, huge magnetic storms are created between them and both stars start to spin faster as a result of tidal forces getting stronger. In Iranian mythology, especially in Persian mythology and in Zoroastrianism, the ancient religion of Persia, Sirius appears as Tishtrya and is revered as the rain-maker divinity (Tishtar of New Persian poetry). Beside passages in the sacred texts of the Avesta, the Avestan language Tishtrya followed by the version Tir in Middle and New Persian is also depicted in the Persian epic Shahnameh of Ferdowsi. Because of the concept of the yazatas, powers which are "worthy of worship", Tishtrya is a divinity of rain and fertility and an antagonist of apaosha, the demon of drought. In this struggle, Tishtrya is depicted as a white horse.

Two and one-half 50.09year orbits following the periastron epoch of 1894.13 gives a date of 2019.34. Bright stars were important to the ancient Polynesians for navigation of the Pacific Ocean. They also served as latitude markers; the declination of Sirius matches the latitude of the archipelago of Fiji at 17°S and thus passes directly over the islands each sidereal day. [34] Sirius served as the body of a "Great Bird" constellation called Manu, with Canopus as the southern wingtip and Procyon the northern wingtip, which divided the Polynesian night sky into two hemispheres. [35] Just as the appearance of Sirius in the morning sky marked summer in Greece, it marked the onset of winter for the Māori, whose name Takurua described both the star and the season. Its culmination at the winter solstice was marked by celebration in Hawaii, where it was known as Ka'ulua, "Queen of Heaven". Many other Polynesian names have been recorded, including Tau-ua in the Marquesas Islands, Rehua in New Zealand, and Ta'urua-fau-papa "Festivity of original high chiefs" and Ta'urua-e-hiti-i-te-tara-te-feiai "Festivity who rises with prayers and religious ceremonies" in Tahiti.
