Alpha Sextantis
Alpha Sextantis (α Sex, α Sextantis) is the brightest star in the equatorial constellation of Sextans. It is visible to the naked eye on a dark night with an apparent visual magnitude of 4.49. The distance to this star, as determined from parallax measurements, is around 280 light years. This is considered an informal "equator star", as it lies less than a quarter of a degree south of the celestial equator. In 1900, it was 7 minutes of arc north of the equator
V1315 Aquilae
V1315 Aquilae is a cataclysmic variable star located in the constellation of Aquila. It is a type of cataclysmic variable known as a nova-like variable (NL), specifically a SW Sextantis star. Nova-like variables such as these SW Sextantis stars are characterized as having non-magnetic white dwarfs and do not undergo dwarf-nova eruptions. There is some evidence that SW Sextantis stars may contain a magnetic white dwarf. Being a SW Sextantis star, V1315 Aquilae has a high rate of mass transfer,
