Delta Scuti variable
Fr.: variable δ Scuti
A member of a class of → pulsating stars with periods less than 0.3 days, → spectral types A or F, and visual light amplitudes in the range from a few thousands of a magnitude to about 0.8 mag. On the → H-R diagram, δ Scuti stars form a group which lies in an → instability strip which includes the classical → Cepheids at its brightest end and the pulsating → white dwarfs at its faintest limit. These stars can show very complex light variations since, while some of them are pulsating in one radial mode only, others may be pulsating simultaneously in several radial and non-radial modes.

Fr.: Ecu de Sobieski
The Shield. A small constellation in the southern Milky Way, at 18h 40m right ascension, 10° south declination. Its brightest star has a visual magnitude of 3.85. Scutum contains several open clusters, as well as a globular cluster and a planetary nebula. The two best known deep sky objects in Scutum are M11 (NGC 6705), a dense open cluster, and M26, another open cluster also known as NGC 6694. The globular cluster NGC 6712 and the planetary nebula IC 1295 can be found in the eastern part of the constellation. Abbreviation: Sct; Genitive: Scuti.
Scutum was created by Johannes Hevelius in 1683, who originally named it L. Scutum Sobiescianum "the shield of Sobieski" to commemorate the victory of the Polish forces led by King John III Sobieski in the Battle of Vienna, and thus refers to Sobieski's Janina Coat of Arms. Later, the name was shortened to Scutum "shield."
