   "Metallicities of Classical Cepheids in the Inner Galactic Disk"
   銀河系中心から3∼ 5.5キロパーセクに位置するセファイドの金属量[Fe/H]を計測し、今まで調べられていなかった銀河系円盤内縁部の金属量勾配を明らかにしました。チリ・ラスカンパナス天文台のマゼラン望遠鏡(口径6.5m)にWINERED分光器を設置して行った観測にもとづく最初の論文です。

   "A Very Metal-poor RR Lyrae Star with a Disk Orbit Found in the Solar Neighborhood"
   太陽系近傍(約1kpc)に非常に金属量の低いRRライリ型変光星を発見しました。木曽シュミット望遠鏡で行ったKISOGP変光星探査で見つけた変光星を、WINERED近赤外線光分散分光器で観測したところ、太陽の100分の1よりも低い金属量をもつことがわかりました。さらに、RRライリ型変光星としてはめずらしく銀河系円盤の中を回転している運動を持つこともわかり、どのような起源を持つのか今後の研究が楽しみです。

   "Discovery of carbon-rich Miras in the Galactic bulge"
   世界で初めて銀河系バルジの中に炭素過多のミラ型変光星(すすに覆われた変光星)を発見しました。(理学系研究科のプレスリリース)
   
   
7. Matsunaga et al., 2016, MNRAS, 462, 414-420 (9 pp.) (ADS)
   "A lack of classical Cepheids in the inner part of the Galactic disc"
   銀河系の中心方向付近に対するセファイド変光星を行った結果、 中心から半径約8千光年の範囲に、若い星がほとんど存在しない 「すき間」があることを、世界で初めて恒星の分布図に基づいて発見しました。 プレスリリースを行いました。(東大理学系からのリリース、英王立天文学協会からのリリース)
   
   
8. Matsunaga et al., 2015, ApJ, 799, id. 46 (9 pp.) (ADS)
   "Kinematics of Classical Cepheids in the Nuclear Stellar Disk"
   2011年に銀河中心付近に発見したセファイド変光星の視線速度を、すばる望遠鏡を 用いた近赤外線高分散分光観測で測定しました。その結果は、Nuclear Stellar Disk と呼ばれる銀河系中心の周囲にあるディスクと同じ回転をしていることを 支持するものでした。将来、視線速度だけでなく固有運動(接線方向の速度)を 測定してセファイドの運動がわかれば、ディスク中の星の形成や進化について 詳しい議論ができるようになると期待されます。
   
   
9. Matsunaga et al., 2013, MNRAS, 429, 385-397 (ADS)
   "Cepheids and other short-period variables near the Galactic Centre"

10. Matsunaga, 2012, Astrophysics and Space Science, 341, 93-98 (ADS)
    "A discussion on metallicity effects on the period-luminosity relations of Cepheids and Miras"
    銀河系中心とマゼラン銀河の観測データにもとづいて、セファイドとミラの周期光度関係(2.2ミクロン)が金属量に依存するかどうかを調べました。金属量依存性がもしあるとしても、0.1-0.15等級よりも小さい程度でしかないということがわかりました。
    
    
11. Matsunaga et al., 2011, Nature, 477, 188-190 (ADS)
    "Three classical Cepheid variable stars in the Nuclear Bulge of the Milky Way"
    IRSF望遠鏡で行った観測から、銀河系のバルジ中心部に3つの古典的セファイド 変光星を発見しました。3つのセファイド変光星の周期はいずれも約20日で 年齢が約2500万年であることがわかりました。 さらに、3000〜7000万年前に生まれたと考えられるセファイド変光星は 見つかりませんでした。この結果は、バルジ中心部での星形成率が 変化することを示しています。 くわしくは、こちらをご覧ください。

    "Period-luminosity relations of type II Cepheids in the Magellanic Clouds"
    2009年の論文(MNRAS, 397, 933)に引き続き、小マゼラン銀河にある２型セファイドの 周期光度関係を調べました。２つのマゼラン銀河の距離指数の差は約0.4等となり、 古典的セファイドの周期光度関係など他の方法で求めた値とおおよそ一致しました ２型セファイドの 周期光度関係が異なる銀河でも共通していて、 距離指標として有効であることを示しています。
