Coins of Ceos exhibit the head of Aristaeus and Sirius in the form of a dog crowned with rays.
On the 18th of January 1788 Admiral Phillip and Captain Hunter arrived in Botany Bay in the " Supply " and " Sirius," followed by six transports, and established a colony at Port Jackson.
Its approach was announced by the appearance of a certain star, Sirius, and as soon as that star was seen above the horizon the people hastened to remove their flocks to the higher ground and abandoned the lower pastures to the fertilizing influence of the stream.
Thus, in the later Avesta, we find not only Mithra but also purely popular divinities such as the angel of victory, Verethraghna, Anahita (Anaitis), the goddess of the water, Tishrya (Sirius), and other heavenly bodies, invoked with special preference.
Dr Chase's measures with the Yale heliometer indicated for it, in 1894, a parallax of about o" ï¿½ 035; 2 and it must, accordingly, be of nearly four times the total brightness of Sirius, while its aerial lustre exceeds seventyfold that of the solar photosphere.
Maskelyne's first contribution to astronomical literature was "A Proposal for Discovering the Annual Parallax of Sirius," published in 1760 (Phil.
As Bruges was accessible by canal from Ostend, Ostend was to be blocked at the same time by the old cruisers" Brilliant "and" Sirius."The main obstacle to th3 enterprise lay in the powerful batteries.
Godsal) and "Sirius" (Lt.-Comm.
The "Sirius" and "Brilliant" shaped course for Ostend, the "Thetis" and her companions eased down.
Alfred Godsal) and "Sirius" (Lt.
The "Sirius" behind her grounded too.
Among them the bright star Sirius was any I in special esteem; it was a goddess Sothis (Sopde), often be 1tified by the Egyptians with Isis.
Such were the calendrical feasts, called ~ the beginnings of the seasons, and including, for example, the monthly and halfmonthly festivals, that of the New Year and that of the rising of Sirius (Sothis).
Professor Petrie, however, thinks it best, while accepting the evidence of the Sirius date, to suppose further that a whole Sothic period of 1460 years had passed in the interval, making a total of 1650 years for the six dynasties in place of 220 years.
For the next ten years it slowly increased (though with slight check), and in 1843 was nearly as bright as Sirius; since then it has slowly faded, but it was not till 1869 that it ceased to be visible to the naked eye.
Hertzsprung has shown that Sirius also belongs to this same system and shares its motion, notwithstanding that it is in a nearly opposite part of the sky.
A possible change of colour in the case of Sirius is noteworthy.
In modern times Sirius has always been a typical white or bluish-white star, but a number of classical writers refer to it as red or fiery.
There is perhaps room for doubt as to the precise significance of the words used; but the fact that Ptolemy classes Sirius with Antares, Aldebaran, Arcturus, Betelgeux and Procyon as " fiery red " (inrorceppoc) as compared with all the other bright stars which are " yellow " (;av©oc) seems almost conclusive that Sirius was then a redstar.
Or " Sirian " type includes most of the bright white stars, such as Sirius, Vega, Rigel, &c.; it is characterized by strong broad hydrogen lines, which are often the only absorption lines visible.
Then follows a gradual absorption of first the helium and then the hydrogen, the photosphere grows continually cooler, and the star passes successively through the stages exemplified by Sirius, Procyon, the Sun, Arcturus and Antares.
Thus it is found that Procyon gives about three times as much light as the sun in proportion to its mass, Sirius about sixteen times, and Orionis more than ten thousand times.
Thus the faint companion of Sirius is of nearly the same mass.
These are the white stars, and the most prominent examples are Sirius, Vega and Procyon.
He announced in 1844 the binary character of Sirius and Procyon from their disturbed proper motions; and was preparing to attack the problem solved later by the discovery of Neptune, when fatal illness intervened.
" Sirius" of 20 guns, the armed trader " Supply," three store-ships and six transports, left England on 17th May 1787, and after touching at Tenerife, Rio de Janeiro, and the Cape of Good Hope, arrived at Botany Bay on the 20th of January 1788, under the command of Captain Arthur Phillip, R.N., with Captain John Hunter, R.N., as second.
As sea-nymphs, they represent the treacherous calm of ocean, which conceals destruction beneath its smiling surface; or they signify the enervating influence of the hot wind (compare the name Sirius), which shrivels up the fresh young life of vegetation.
In this case the companion, being about half the mass of Sirius itself, has probably cooled more rapidly, and on that account emits much less light.
From comparisons between the observed places of Arcturus, Aldebaran and Sirius and the places assigned to them by Alexandrian astronomers, he was led to the opinion that all three are moving towards the south (Phil.
The group consisting of five stars of Ursa Major together with Sirius has already been alluded to; another very marked group of 16 stars in Perseus, all of the Helium type of spectrum, form a similar association.
