List of the brightest stars

from Wikipedia, the free encyclopedia

The following list of the brightest stars shows the 100 brightest stars as seen from the earth according to their apparent brightness . Of the total electromagnetic radiation , only the parts of visible light are taken into account. For the ranking, the average value of the apparent brightness was used for variable stars , and the combined visual brightness for non-separable components of double or multiple stars .

For comparison, in addition to the sun , very bright celestial objects such as the Earth's moon and some planets of the solar system are listed.

visibility

The stars that are always in the sky in Central Europe do this all in its northern half. They “circle” around the North Star , which is at 50 ° north latitude (corresponds roughly to the confluence of the Main into the Rhine near Mainz ) all day and year at exactly this angle above the horizon in the north. The other stars are highest when they are due south. Then they are 40 ° (or in Klagenfurt 43.4 °, in Flensburg only 35 °) higher than their declination above the horizon.

The right ascension now indicates by how many hours this position deviates from the noon position of the sun at the beginning of spring . A star with a right ascension of 0 h and a declination of 0 ° would e.g. B. at the beginning of spring exactly with the sun at noon at 40 ° (Klagenfurt: 43.4 °; Flensburg: 35 °) above the horizon. However, he would be invisible to us at this point in time. It would be best visible exactly six months later, at the beginning of autumn, at midnight.

A star that had a right ascension of 2 hours would be rotated relative to this by 2/24 = 1/12. One twelfth of a year, i.e. one month, after the beginning of spring, it would be in the south with the sun and six months later, i.e. around October 21, at midnight in the south.

midnight

The Central European Standard Time (colloquially often winter time) is based on the actual time on the 15th eastern longitude, at which Görlitz is located in the far east of Germany. There it is actually midday at 12 noon and midnight at midnight during normal time, and one hour later in summer during summer time . In Aachen , on the 6th degree of longitude, this time is shifted backwards by the 36 minutes that the sun is later there in the south. Also in Bern or Basel (just under or a good 7.5 °) the sun is only half an hour later than in Görlitz, while in the east of Vienna (16.5 °) it was 6 minutes earlier.

For the fictional star with right ascension 0 h and declination 0 ° this would mean that it would be at its zenith at the beginning of autumn, when summer time still applies, at 0:54 a.m. in the Vienna night sky and at 1:36 a.m. in the Aachen night sky, and exactly as high as the sun on the preceding and following noon.

Sample calculation

Sirius , the brightest star in the earthly sky, has a declination of around −17 ° and a right ascension of 06 h 45 m. In Mainz it is a maximum of 23 ° above the horizon and is 3 months and about 11 days after the beginning of spring, i.e. the beginning of July, with the sun in the south, which makes it invisible. In Mainz it will therefore be at midnight at the beginning of January, at 8.3 ° east longitude that is 0:27 in standard time, in the south.

The Aldebaran , the brightest star in Taurus , has its southern position at 56.5 ° due to a declination of + 16.5 ° and is there with the sun about 2 months and 9 days later, i.e. at the beginning of June, due to a right ascension of 4 h 36 m . The fact that this does not fall into the zodiac sign Taurus , but into the next one, the Gemini , is due to the precession of the earth's axis ( migration of the spring equinox ) - since 1700 to 3000 years the constellation has shifted by around a month. At the beginning of December, Aldebaran is in the south at midnight.

list

For comparison, the list includes the sun, the moon and the brightest planets with a green background and without rank.

In Central Europe (50 ° N; corresponds roughly to the confluence of the Main in the Rhine near Mainz) the 28 brightest stars with declination below -40 ° are never visible; their lines are darkened. In the extreme south of Austria (Klagenfurt: 46.6 ° N) and German-speaking Switzerland this would be only 23, in the extreme north of Germany (55 ° N; Flensburg) 31.

Conversely, in Central Europe the 20 of the brightest stars are always above the horizon with a declination of over + 40 °; their lines are highlighted. In Klagenfurt this number would decrease to 17, in Flensburg it would increase to 22. Stars of the just to the north never-setting which is Vega , the fifth-brightest star and in Central Europe even the third brightest, starting from a line Dusseldorf - Leipzig throughout the night sky. Since a very large proportion of the German population (Ruhr area, Berlin, Hamburg) lives north of this line, it was also highlighted. It can also be clearly seen further south, at least on every clear night, although not always throughout the night.

It should be noted that the five stars darkened here, which are theoretically still visible from Klagenfurt, are only there for a very short period of time in the year and only directly above the horizon, which is why they are clear because of a longer light path through the atmosphere appear darker than the value in the table indicates.

Past and future

Due to the proper movement of both the sun and the other stars within the Milky Way, their distances to one another change and thus also the apparent brightness, viewed from Earth, changes over long periods of time. Sirius has been the brightest star in the sky from Earth (apart from the Sun) for about 90,000 years. Canopus had previously held this rank several times , while Wega will replace Sirius as the brightest star in around 210,000 years . In the past five million years there have also been a few stars that appeared significantly brighter from Earth than Sirius does today. Adhara (ε Canis Majoris) reached an apparent brightness of almost −4 mag almost five million years ago , comparable to the planet Venus .

The following list from 1998 contains the brightest stars from Earth within the last and next five million years. By evaluating the new Gaia satellite data, it was later discovered that Gliese 710 will probably reach a brightness of −2.7 mag in 1.35 million years and will therefore be the brightest star on earth at this point in time.

Remarks

  1. The apparent brightness only makes up part of the bolometric total brightness , to which the radiation emitted over the entire electromagnetic spectrum contributes.
  2. Also circumpolar stars are highest when they are in the south - if its declination is smaller than the latitude of the observation site. Alkaid , the front drawbar star of the Big Dipper (49 °), is at the 50th parallel z. B. 9 ° high in the north and 89 ° in the south. Only z. E.g. with Alioth (also Big Dipper, 56 °) the statement is wrong, also arithmetically. In the "south" it is raised by 40 ° to 96 °, which means that it is 84 ° high in the north. Stars that have a higher declination than the latitude from which they are observed have both their highest and lowest levels in the north.
