57 Tauri, also known as h Tauri and V483 Tauri, is a star 148 light years from the Earth, in the constellation Taurus. [2] It is a 5th magnitude star, so it will be visible to the naked eye of an observer located far from city lights. [3] 57 Tauri is a member of the Hyades star cluster. [11] It is a Delta Scuti variable star, whose brightness changes slightly, ranging from magnitude 5.55 to 5.59. [3]

In 1908, Lewis Boss listed 57 Tauri as a member of the Hyades cluster based upon its proper motion agreeing with the motions of other cluster members. [12] Its membership in the cluster was firmly established forty-four years later by Hendrik van Bueren, using both proper motion and radial velocity. [13] 57 Tauri is located 10.8 light years from the core of the Hyades cluster. [14]

Robert Millis discovered that 57 Tauri is a variable star, in 1967. He reported that the amplitude varied by 0.02 magnitudes with a period of 1.5 hours. [15] In 1972, it was given the variable star designation V483 Tauri. [16] A year 2000 study of 57 Tauri, based on 54 nights of photometric data, identified twelve pulsation frequencies ranging in period from 58.6 minutes to 6.17 days. [11]

In 1999, Anthony Kaye discovered that 57 Tauri is a spectroscopic binary by examining 139 high signal-to-noise spectra obtained at Kitt Peak. [7]
