Chinese astronomers have
discovered the most lithium-rich giant star ever known, which could shed new
light on the evolution of the universe.
With 3,000
times more lithium than a normal star, it was found in the direction of
Ophiuchus, on the north side of the galactic disk, at a distance of 4,500 light
years from Earth, reports Xinhua news agency. The star
has a mass almost 1.5 times our sun.
A research
team, led by astronomers from National Astronomical Observatories of China
(NAOC), made the discovery with the Large Sky Area Multi-Object Fibre
Spectroscopic Telescope (LAMOST), a special quasi-meridian reflecting Schmidt
telescope located in NAOC's Xinglong Observatory, in Hebei province.
The telescope can observe
about 4,000 celestial bodies at one time and has made a massive contribution to
the study of the structure of the galaxy.
Lithium is considered one of
the three elements synthesised in the Big Bang, together with hydrogen and
helium. The abundance of the three elements was regarded as the strongest
evidence of the Big Bang.
The evolution of lithium has
been a key subject in the research of the evolution of the universe and stars.
However, giant stars rich in lithium are very rare, with only a few found over
the past three decades. This makes their study remarkably challenging, said
Zhao Gang, a lead astronomer at NAOC.
"The discovery of this
star has largely increased the upper limit of observed lithium abundance,"
said Zhao.
I hope so many readers don’t
familiar about the lithium and use of lithium. Now I would like to write in
short about the lithium.
What
is Lithium?
OTHER NAME(S): Atomic number
3, Carbonate de Lithium, Citrate de Lithium, Li, Lithium Carbonate, Lithium
Citrate, Lithium Orotate, Litio, Numéro Atomique 3, Orotate de Lithium.
Lithium is an element. It
gets its name from “lithos,” the Greek word for stone, because it is present in
trace amounts in virtually all rocks. Lithium works with other elements, drugs,
enzymes, hormones, vitamins, and growth factors in the body in many different
ways. People use it for medicine.
Use
of Lithium
Lithium is used for mental
illnesses, including bipolar disorder, depression, and schizophrenia; for
eating disorders, including anorexia and bulimia; and for blood disorders,
including anemia and low white-cell count (neutropenia).
Lithium is also used for
headache, alcoholism, epilepsy, diabetes, liver disease, kidney disorders,
arthritis, a skin condition called seborrhea, and overactive thyroid. Other
uses include treatment of asthma, Huntington’s disease, Graves' disease, herpes
simplex, a movement disorder called tardive dyskinesia, Tourette’s syndrome,
cyclical vomiting, Meniere's disease, a tingling or “crawling” sensation in the
skin (paresthesias), and aggressive behavior in people with attention
deficit-hyperactivity disorder (ADHD).
Side effects Of Lithium
About 75% of people who take
lithium for bipolar disorder have some side effects, although they may be
minor. They may become less troublesome after a few weeks as your body adjusts
to the drug. Sometimes, side effects of lithium can be relieved by tweaking the
dose. However, never change your dose or drug schedule on your own. Do not
change the brand of lithium without checking with your doctor or pharmacist
first. If you are having any problems, talk to your doctor about your options.
