Star in the constellation Aries
VZ Arietis is single,
[10] white-hued star in the northern
zodiac
constellation of
Aries . Varying between magnitudes 5.82 and 5.89,
[3] the star can be seen with the naked eye in dark, unpolluted areas. Based upon an annual
parallax shift of 5.8
mas ,
[1] it is located 560
light years from the Sun. It is moving further away with a heliocentric
radial velocity of +14 km/s.
[5] The star was formerly known as 16 Trianguli , but as the star is no longer in the constellation
Triangulum , this designation has fallen out of use.
[11]
This is a
chemically peculiar star
[6] of type CP2 (
Ap star ),
[12] showing an anomalous abundance of silicon in its
spectrum .
[13] It has a
stellar classification of A0 V,
[4] which indicates this is an
A-type main-sequence star that currently fusing hydrogen into helium in its core. This is an
Alpha2 Canum Venaticorum variable
[12] with 2.7
[6] times the
mass of the Sun and about 3.1
[7] times the
Sun's radius . It is radiating 79 times the
Sun's luminosity from its
photosphere at an
effective temperature of 10,304 K.
