Aldebaran ist ein Doppelsternsystem in etwa 67 Lichtjahren (20 Parsec) Entfernung. Therefore, Aldebaran in no way interact with the Hyades, is not considered to be part of the asterism, and its exact origins remain unknown, since it cannot be linked to any structure, cloud, or group of stars.

But in 2018, a team of astronomers reported a new number: 1.16 times the mass of the Sun. The way they move can reveal the star’s mass. Er ist mit einer unregelmäßigen Periode bei einer Helligkeitsschwankung von 0,2 mag leicht veränderlich. Nonetheless, the stars’ solar wind continues outward up to the termination shock boundary, which is where it collides with the (hot) ionized interstellar medium that predominates in the Local Bubble, a roughly spherical astrosphere that stretches outward from Aldebaran to a distance of about 1,000 AU. … The newer study measured not only that, but vibrations on the surface of Aldebaran. Allowance for infrared radiation reveals the star to have a fairly high luminosity 425 times that of the Sun, which leads to a radius of 43 times solar. The team was studying a planet that orbits Aldebaran. The resulting collapse of the core has ignited a remaining shell of hydrogen surrounding it, which has subsequently overcome the inward pushing force of the gravity of the star’s outer layers, thereby causing it to swell up to around 44.2 solar masses.

• Age: 7 billion years Science of Aldebaran. The stars’ photosphere displays carbon, oxygen, and nitrogen abundances, which suggests the first dredge-up stage in the life cycle of Aldebaran, a normal step in the evolutionary process of red giant stars that involves “dredging” up material from the star’s deep interior by means of convection currents, which then gets mixed into the star’s outer layers. The star was likewise worshiped by the Babylonians, who called the constellation Gud.Anna (“Bull of Heaven“), while to the ancient Egyptians it represented the bull-god Orissi. This gives it the appearance of being the most luminous star in the V-shaped asterism that marks out the “head” of the Bull, but recent measurements have shown that the five brightest stars which make up the Hyades asterism lie 151 light years away compared to the 65 light years distant Aldebaran.
