Zodiacal constellations are quite popular: many seek to find a picture of their astrological sign above their heads. The task is often not so simple, because some of them are losing in brightness to many other celestial images. Among these are the constellation Aries. About him and will be discussed below.
High in the sky
The Aries constellation can be observed throughout the vast territory of our country. The ideal period for this begins at the end of summer and ends with the departure of winter. Aries is located high above the head. As a reference point, it is recommended to use brighter celestial drawings, located next to: Taurus and Gemini immediately follow him, to the north one can observe Perseus and the Triangle.
Since the stars in the constellation Aries are not noticeable enough, it is better to admire this zodiac sign in conditions of cloudless weather and the absence of artificial lighting. For the naked eye in this case, about fifty luminaries become available.
Beautiful images on old maps give only an approximate idea of what the constellation Aries looks like in the sky. In the figure created by the luminaries, it is very difficult to guess a pretty lamb with twisted horns.
The main and most recognizable element of the celestial image is an arc of three stars. These are Gamal, Sheratan and Mizartim - the brightest points of the picture. They are also referred to as alpha, beta and gamma of Aries, respectively. The arc is easy to spot in the sky: it is located south of the constellation of the Triangle.
Thinkers of the past studied all the constellations of the zodiac. Aries, however, is considered one of the most famous among them. In addition, this celestial drawing is included in Ptolemy's Almagest, which contained a list of all constellations known in the era of Antiquity. In antiquity, increased attention was paid to Aries because more than two thousand years ago there was a point of the vernal equinox in it.
It should be noted that since the appearance of the first astrological knowledge in the sky, literally much has changed. The sun today visits the zodiac constellations is not at all in those periods that are laid in horoscopes. In Aries, for example, it “stays” from April 19 to May 13. Astrological and astronomical ideas about the zodiacal constellations, therefore, diverge greatly.
The constellation Aries for children often first occurs in the lessons on the history of culture during a study of the myths of Ancient Greece. It is believed that this celestial figure represents the lamb with the Golden fleece for which the Argonauts went. Associated with Aries and another legend. It is a lamb with Golden hair rescues two children Freksa and Hull, who were commanded to sacrifice to the gods wicked stepmother. In reward for this act he was immortalized in the sky among the stars.
If you go back to the stars of Aries, then the most notable among them is Gamal. The name of the light is translated from Arabic as "the head of a ram." Gamal is a star of the second magnitude. According to researchers, at least one planet rotates around it. The information obtained suggests that it is about 1.8 times as large as Jupiter and revolves around its star for 380 days.
The next in brightness among the stars that make up the constellation of Aries is the beta of this heavenly pattern, or Sheratan. It is a dual system. Its main element is the white star of the main sequence, located at a distance of 59.6 light years from the Sun. A companion rotates around it, making one revolution in about 107 days. Presumably the second star belongs to the spectral class G.
One of the most interesting luminaries of this heavenly pattern is Mizartim. Aries Gamma is a triple star system, 204 light years away from the Sun. Despite its relative dullness (the third magnitude), in ancient times, Mezartim was called the first star of Aries, since the vernal equinox point was located next to it.
One of the components of the system is a double star. Its components can be distinguished in small telescopes, since they are separated by a sufficient distance for this. Both elements are white main sequence stars. They rotate with an orbital period exceeding five thousand years.
The third star of the system moves around the described pair and is dimmer. It belongs to the spectral class K.
The Aries constellation in different sources is often described as not possessing particularly interesting objects. However, there are elements on its territory worthy of attention. For example, BD + 20 ° 307. This is a spectral double star, located at a distance of three hundred light years from the sun. Her system is a pair of companions, in general, similar to our star, only slightly superior to it in mass. Both elements rotate around a common center of mass for a rather short period — 3.42 days.
However, the feature of the star is not in it. A pair of luminaries is surrounded by a dense dust cloud consisting of very small and strongly heated particles. A similar formation exists in the solar system, but here it is characterized by a much lower density. According to scientists, the dust that makes up the cloud should have fallen on the components of the system for a long time or left a pair of luminaries under the influence of the stellar wind. The reasons for such a high density of particles are not yet completely clear. One hypothesis explains the existence of a cloud by the fact that several thousand years ago two planets collided in the system, comparable in size to Earth or Venus.
Another interesting object – the light, denoted as TT RAM. It is the brightest variable star in the sky, and therefore the most studied. The amount of data on TT RAM, however, does not mean that scientists know all about it. Still remains unclear until the end the mechanism flashes the lights. The brightness of a star is wont to rise and fall in unpredictable ways. Recent studies allow us to classify the TT RAM to noviodunum cataclysmic variables, however, the question about the mechanism of the outbreak is not considered to be solved.
The Aries constellation in the sky seems rather dim in comparison with some neighbors, however, it is also rich in its stories and secrets. Such pictures, written by the Universe itself, seem to remind people that something small and seemingly insignificant can hide something interesting and worthy of close attention.
