Karakul sheep the terms for newborn lambs' and fetal lambs' pelts are used interchangeably. The newborn lambs have a tight, curly pattern of hair. The lambs must be under three days old when they are killed, or they will lose their black color and soft, tightly wound coils of fur. Dark colors are dominant and lambs often darken in color as they age. Fetal karakul lamb pelts are called broadtail, "Breitschwanz" (German), and "karakulcha". Fetal karakul lambs are harvested through miscarriages, induced early delivery or by killing the mother sheep and removing the fetus. Rather than killing healthy female sheep, farmers will
A-type main-sequence star also occasionally sees Delta Leonis (A4 V) listed as a standard. There are no published A6 V and A8 V standard stars. A-type stars are young (typically few hundred million years old) and many emit infrared (IR) radiation beyond what would be expected from the star alone. This IR excess is attributable to dust emission from a debris disk where planets form. Surveys indicate massive planets commonly form around A-type stars although these planets are difficult to detect using the Doppler spectroscopy method. This is because A-type stars typically rotate very quickly, which makes it difficult to measure the small
