HD 93194 (HR 4205) is a star in the constellation Carina. Its apparent magnitude is 4.79. Its parent cluster is IC 2602.

HD 93607 is a B4 main sequence star, notable for "nebulous" absorption lines caused by its rapid rotation. [3] It is included on a list of the least variable stars amongst those observed by the Hipparcos satellite, with a possible variation less than 0.01 magnitudes. [10]

Chi Tauri, Latinised from χ Tauri, is a star system in the constellation of Taurus. Parallax measurements made by the Hipparcos spacecraft put it at a distance of about 291 light-years from Earth. The primary component has an apparent magnitude of about 5.4, meaning it is visible with the naked eye.

28 Andromedae is a Delta Scuti variable star in the constellation Andromeda. 28 Andromedae is the Flamsteed designation. It also bears the variable star name GN Andromedae. Its apparent magnitude is 5.214, varying by less than 0.1 magnitudes.

<span class="mw-page-title-main">Alpha Chamaeleontis</span> Star in the constellation Chamaleon

Alpha Chamaeleontis, Latinized from α Chamaeleontis, is a solitary star in the southern circumpolar constellation of Chamaeleon. It has an apparent visual magnitude of 4.06 and thus is bright enough to be seen with the naked eye. With an annual parallax shift of 51.12 mas, it is located 63.8 light years from the Sun. The star is drifting closer with a radial velocity of −13 km/s, and is predicted to come to within 47 light-years in 666,000 years.

Gliese 105 is a triple star system in the constellation of Cetus. It is located relatively near the Sun at a distance of 23.6 light-years. Despite this, even the brightest component is barely visible with the unaided eye (see Bortle scale). No planets have yet been detected around any of the stars in this system.

Lambda Caeli, Latinized from λ Caeli, is a star in the constellation Caelum. It is also known by its designations HD 30202 and HR 1518. This star is a challenge to view with the naked eye, having an apparent visual magnitude of 6.24. Based on parallax measurements, Lambda Caeli is known to be around 700 light-years distant from the Sun, but is drifting closer with a radial velocity of −4 km/s.

Tau1 Capricorni is a star in the constellation Capricornus. It has an apparent magnitude of 6.76, making it readily visible in binoculars, but not to the naked eye. Located approximately 750 light years from Earth, the star is receding with a heliocentric radial velocity of 18.5 km/s. Due to its location near the ecliptic, τ1 Cap can be occulted by the Moon and rarely planets.
