Sarin

Sarin, or GB, is a colorless, odorless liquid, used as a chemical weapon owing to its extreme potency as a nerve agent. It is generally considered as a weapon of mass destruction. Production and stockpiling of sarin was outlawed as of April 1997 by the Chemical Weapons Convention of 1993, and it is classified as a Schedule 1 substance. In June 1994, the UN Special Commission on Iraqi disarmament destroyed the nerve agent sarin under Security Council resolution 687 (1991) concerning the disposal of Iraq's weapons of mass destruction.

Sarin is an organophosphorus compound with the formula [(CH₃)₂CHO]CH₃P(O)F. It can be lethal even at very low concentrations, where death can occur within one to ten minutes after direct inhalation of a lethal dose, due to suffocation from lung muscle paralysis, unless some antidotes, typically atropine and an oxime, such as pralidoxime, are quickly administered. People who absorb a non-lethal dose, but do not receive immediate medical treatment, may suffer permanent neurological damage.

Delta Herculis

Delta Herculis (δ Her, δ Herculis) is a fourth-magnitude star in the constellation Hercules. It has the traditional name Sarin.

Properties

Sarin is a complex star system consisting of at least 2 stars and possibly as many as 5. The main star is an A Type main sequence subgiant with a stellar classification A3IV. The subgiant has both a mass and radius that are roughly two times solar yielding a total luminosity of about 18.5 L_☉ Though it only shines with an apparent magnitude of 3.12, it the third brightest star in the Hercules constellation. The most recent Hipparcos data yields a distance estimate of approximately 23.1 parsecs (pc) from Earth or 75 light years (ly).

In culture

In Chinese, 天市左垣 (Tiān Shì Zuǒ Yuán), meaning Left Wall of Heavenly Market Enclosure, refers to an asterism which is represent eleven old states in China which is marking the left borderline of the enclosure, consisting of δ Herculis, λ Herculis, μ Herculis, ο Herculis, 112 Herculis, ζ Aquilae, θ¹ Serpentis, η Serpentis, ν Ophiuchi, ξ Serpentis and η Ophiuchi. Consequently, δ Herculis itself is known as 天市左垣一 (Tiān Shì Zuǒ Yuán yī, English: the First Star of Left Wall of Heavenly Market Enclosure), represent the state Wei (魏), together with 33 Capricorni (φ Capricorni and χ Capricorni in R.H. Allen's version) in Twelve States (asterism).
