Hiwa-i-te-rangi, also known just as Hiwa, is the youngest of Matariki's children and was considered the "wishing star": Māori would rest their hopes and desires on Hiwa, similar to "wishing upon a star", and if it appeared to shine bright and clear on the first viewing of Matariki those individual and collective wishes were likely to be answered.
Botanical illustration of a pōhutukawa sprig by Ellen Cheeseman. Pōhutukawa (Metrosideros excelsa), [2] also known as the New Zealand Christmas tree, [3] [4] or iron tree, [5] is a coastal evergreen tree in the myrtle family, Myrtaceae, that produces a brilliant display of red (or occasionally orange, yellow [6] or white [7]) flowers, each consisting of a mass of stamens.
Once the neutron star enters the red giant, drag between the neutron star and the outer, diffuse layers of the red giant causes the binary star system's orbit to decay, and the neutron star and core of the red giant spiral inward toward one another. Depending on their initial separation, this process may take hundreds of years.
HD 140283 (also known as the Methuselah star) is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy.
One such example of a flower is the pohutukawa (Metrosideros excelsa), which acts to regulate colour in a different way. The pohutukawa contains small petals also having bright large red clusters of stamens. [14] Another attractive mechanism for flowers is the use of scents which are highly attractive to humans. One such example is the rose.
NGC 246's central star is the 12th magnitude [7] white dwarf HIP 3678 A. [8] NGC 246 is not to be confused with the Rosette Nebula (NGC 2337), which is also referred to as the "Skull." [ 9 ] Among some amateur astronomers, NGC 246 is known as the "Pac-Man Nebula" because of the arrangement of its central stars and the surrounding star field.
Theta Ophiuchi appears to be a triple star system. The brightest component is a spectroscopic binary with an orbital period of 56.71 days and an eccentricity of 0.17. The third component is 5.5 magnitude star with a stellar classification of B5. Its angular separation from the binary pair is 0.15 arcseconds. [13]
The orbit of HD 188753 BC around A. The primary star, HD 188753 A, is similar to the Sun [9] with a mass only 6% larger and a stellar classification of G8V. [3] Orbiting this primary at a distance of 12.3 AU [10] is a pair of smaller stars that orbit each other with a period of 156.0 ± 0.1 days, a semi-major axis of 0.67 AU, and eccentricity of 0.1 ± 0.03.
