Apparent magnitude

Apparent magnitude is a measure of the brightness of a star or other astronomical object.

See DS Tucanae and Apparent magnitude

Astronomical transit

In astronomy, a transit (or astronomical transit) is the passage of a celestial body directly between a larger body and the observer.

See DS Tucanae and Astronomical transit

Astronomical unit

The astronomical unit (symbol: au, or AU) is a unit of length defined to be exactly equal to.

See DS Tucanae and Astronomical unit

AU Microscopii

AU Microscopii (AU Mic) is a young red dwarf star located away – about 8 times as far as the closest star after the Sun. DS Tucanae and aU Microscopii are Henry Draper Catalogue objects, Hipparcos objects and objects with variable star designations.

See DS Tucanae and AU Microscopii

Axial tilt

In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, which is the line perpendicular to its orbital plane; equivalently, it is the angle between its equatorial plane and orbital plane.

See DS Tucanae and Axial tilt

Binary star

A binary star or binary star system is a system of two stars that are gravitationally bound to and in orbit around each other. DS Tucanae and binary star are binary stars.

Durchmusterung

In astronomy, Durchmusterung or Bonner Durchmusterung (BD) is an astrometric star catalogue of the whole sky, published by the Bonn Observatory in Germany from 1859 to 1863, with an extension published in Bonn in 1886.

Epoch (astronomy)

In astronomy, an epoch or reference epoch is a moment in time used as a reference point for some time-varying astronomical quantity.

Henry Draper Catalogue

The Henry Draper Catalogue (HD) is an astronomical star catalogue published between 1918 and 1924, giving spectroscopic classifications for 225,300 stars; it was later expanded by the Henry Draper Extension (HDE), published between 1925 and 1936, which gave classifications for 46,850 more stars, and by the Henry Draper Extension Charts (HDEC), published from 1937 to 1949 in the form of charts, which gave classifications for 86,933 more stars. DS Tucanae and Henry Draper Catalogue are Henry Draper Catalogue objects.

Hertzsprung–Russell diagram

The Hertzsprung–Russell diagram (abbreviated as H–R diagram, HR diagram or HRD) is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities and their stellar classifications or effective temperatures.
