And check that the elements that lithium is produced in large amounts.

Yamagata amateur astronomer of, as Itagaki-san was examined in detail the nova explosion that was discovered in "Delphinus" in 2013, was sure that the elements that lithium is produced in large amounts, research teams, such as the National Astronomical Observatory of Japan But I was published in the British science journal Nature of date 19.
Lithium is made early in the universe, it is believed to have been increased by such star explosions, the first time the production of explosion of the star was observed. Universe in the outcome to be a clue to explore whether've been if changes to the current figure, Itagaki-san rejoice as "Luckily it finds phenomenon has led to academic discovery".
Nova explosion, star who finished the life exploded to attract gas from another star, temporarily bright and visible phenomenon. August Itagaki-san 13 years, found a nova explosion at about 14 000 light-years away from Earth. a result of the research team has observed in the Subaru telescope (US Hawaii Island), the mass of the gas that was blown off in the explosion, I was confirmed that the radioactive material change in lithium in about 50 days has been included in the mass.
Itagaki-san addition to have found a nova explosion more than 30, are the last of 101 pieces of "supernova" of Japan most a large explosion discovery of a huge star in until last month. I guess astronomy is in life's work. Please discover a lot more of supernova is working hard to further observation should be noted.



山形市のアマチュア天文家、板垣さんが２０１３年に「いるか座」で発見した新星爆発を詳しく調べたところ、リチウムという元素が大量に生成されているのを確認したと、国立天文台などの研究チームが１９日付の英科学誌ネイチャーで発表した。
　リチウムは宇宙の初期に作られ、星の爆発などで増えてきたと考えられているが、星の爆発での生成が観測されたのは初めて。宇宙が現在の姿にどう変化してきたかを探る手がかりとなる成果で、板垣さんは「運良く見つけた現象が、学問的な発見につながった」と喜ぶ。
　新星爆発は、一生を終えた星が別の星からガスを引き寄せて爆発し、一時的に明るく見える現象。板垣さんは１３年８月、地球から約１万４０００光年先で新星爆発を見つけた。研究チームがすばる望遠鏡（米ハワイ島）で観測した結果、爆発で吹き飛ばされたガスの塊に、５０日ほどでリチウムに変化する放射性物質が大量に含まれていたことを確認した。
　板垣さんは新星爆発を３０個以上見つけているほか、先月までに巨大な星の最後の大爆発である「超新星」を日本最多の１０１個発見している。天文がライフワークになっているんでしょうね。なお一層の観測に励んでもっと多くの超新星を発見してください。
