Zodiacal constellations are quite popular: many seek to find a picture of their astrological sign above their heads. The task in this case is often not so simple, because some of them in brightness lose many other heavenly images. The constellation of Aries is one of these. About him and will be discussed below.
High in the sky
The constellation of Aries 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 high above his head. As indicative landmarks it is recommended to use more bright celestial drawings, located near: Taurus and Gemini follow immediately after it, to the north you can see Perseus and Triangle.
Since the stars in the constellation of Aries are not sufficiently noticeable, admiring this sign of the Zodiac is better in conditions of cloudless weather and lack of artificial lighting. Approximately fifty luminaries are available for the naked eye in this case.
Beautiful images on old maps give only an approximate idea of how the constellation of Aries in the sky looks. 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. This Gamal, Sheratan and Mezartim - the brightest points of the picture. Also they are denoted as alpha, beta and gamma of Aries, respectively. The arc is easy to detect in the sky: it is located south of the constellation of the Triangle.
The most ancient
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 heavenly figure is included in the "Almagest" of Ptolemy, containing a list of all the constellations known in the Antiquity. In ancient times, special attention was paid to Aries, because in it more than two thousand years ago there was a point of the spring equinox.
It should be noted that since the appearance of the first astrological knowledge in the sky, in a literal sense, much has changed. The sun today visits the zodiacal constellations at all in those periods that are laid in horoscopes. In Aries it, for example, "visits" from April 19 to May 13. Astrological and astronomical representations about the zodiacal constellations, thus, strongly diverge.
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 we return to the stars of Aries, the most notable among them is Gamal. The name of the luminary is translated from Arabic as "the head of a ram". Gamal is a star of the second magnitude. According to the researchers around her, at least one planet rotates. The information obtained suggests that by mass it exceeds Jupiter by approximately 1.8 times and turns around its star in 380 days.
The next brightest among the stars, constituting the constellation of Aries, is the beta of this heavenly figure, 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 revolves around it, making one revolution in about 107 days. Supposedly, the second star belongs to the spectral class G.
One of the most interesting luminaries of this heavenly drawing is Mezartim. Gamma Aries is a triple star system, distant from the Sun at a distance of 204 light years. Despite its relative dullness (the third magnitude), Mezartim in ancient times was called the first star of Aries, since it was near it that the point of the spring equinox was located.
One of the components of the system is a double star. Its components can also be distinguished in small telescopes, since they are separated by a sufficient distance for this purpose. Both elements are white stars of the main sequence. They rotate with an orbital period of more than 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 constellation of Aries in different sources is often described as having no particularly interesting objects. However, on its territory there are elements 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. Its system is a pair of companions, on the whole similar to our luminary, only slightly surpassing it by mass. Both elements rotate around the common center of mass in a fairly short period - 3.42 days.
However, the peculiarity of the star is not in this. 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 much less dense. According to scientists, the dust that makes up the cloud should have long fallen on the components of the system or leave a pair of stars under the action of a stellar wind. The reasons for such a high density of particles are not yet fully understood. One of the hypotheses explains the existence of the cloud by the fact that several thousand years ago two planets collided in the system, comparable in size to the 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 constellation of Aries in the sky seems rather lackluster in comparison with some neighbors, however it is also rich in its stories and secrets. Similar pictures written by the Universe itself, seem to remind people that there can be something interesting and worthy of close attention behind the small and seemingly insignificant.
