SIMBAD data

HD 1606 is a single [12] star in the northern constellation of Andromeda, positioned a few degrees to the northeast of the bright star Alpheratz. It has a blue-white hue and is dimly visible to the naked eye with an apparent visual magnitude of 5.87. [2] Although it is suspected of variability, none has been conclusively found. [13] The star is located at a distance of approximately 580 light-years (179 parsecs ) from the Sun based on parallax, [1] and is drifting further away with a radial velocity of +4 km/s. [7] It has an absolute magnitude of −0.5. [8]

This is a B-type main-sequence star with a stellar classification of B7V, [4] which means it is currently generating energy through hydrogen fusion at its core. It has 3.75 [3] times the mass of the Sun and a fairly high rate of spin, showing a projected rotational velocity of 113 km/s. [10] The star is radiating 245 [3] times the luminosity of the Sun from its photosphere at an effective temperature of 13,186 K. [10]

<span class="mw-page-title-main">26 Andromedae</span> Star in the constellation Andromeda

26 Andromedae, abbreviated 26 And, is a binary star system in the constellation Andromeda. 26 Andromedae is the Flamsteed designation. It has a combined apparent visual magnitude of 6.10, which is near the lower limit of visibility to the naked eye. The distance to this system can be estimated from its annual parallax shift of 5.35 mas, which yields a distance of about 600 light years.

With an apparent visual magnitude of +4.89, it is a faint star but visible to the naked eye. Based upon an annual parallax shift of 7.92 mas as seen from Earth, this star is located around 410 light years from the Sun. Cowley et al. (1969) catalogued this star with a stellar classification of B9 III, indicating it has the spectrum of an evolved B-type giant star. However, Palmer et al. (1968) assigned it a class of B8 V, which would instead suggest it is an ordinary B-type main-sequence star.
