Distortion of Magnetic Fields in a Starless Core II: 3D Magnetic Field Structure of FeSt 1-457
Ryo Kandori, Motohide Tamura, Kohji Tomisaka +6
Three dimensional (3D) magnetic field information on molecular clouds and cores is important for revealing their kinematical stability (magnetic support) against gravity which is f…
Exoplanets around Low-mass Stars Unveiled by K2
Teruyuki Hirano, Fei Dai, Davide Gandolfi +38
We present the detection and follow-up observations of planetary candidates around low-mass stars observed by the K2 mission. Based on light-curve analysis, adaptive-optics imaging…
Red-edge position of habitable exoplanets around M-dwarfs
Kenji Takizawa, Jun Minagawa, Motohide Tamura +2
One of the possible signs of life on distant habitable exoplanets is the red-edge, which is a rise in the reflectivity of planets between visible and near-infrared (NIR) wavelength…
The Fundamental Stellar Parameters of FGK Stars in the SEEDS Survey
Evan A. Rich, John P. Wisniewski, Michael W. McElwain +59
Large exoplanet surveys have successfully detected thousands of exoplanets to-date. Utilizing these detections and non-detections to constrain our understanding of the formation an…
Distortion of Magnetic Fields in a Starless Core: Near-Infrared Polarimetry of FeSt 1-457
Ryo Kandori, Motohide Tamura, Nobuhiko Kusakabe +6
Magnetic fields are believed to play an important role in controlling the stability and contraction of dense condensations of gas and dust leading to the formation of stars and pla…
Multi-Color Simultaneous Photometry of the T-Tauri Star Having A Planetary Candidate CVSO 30
Masahiro Onitsuka, Akihiko Fukui, Norio Narita +4
We present three-band simultaneous observations of a weak-line T-Tauri star CVSO~30 (PTFO~8-8695), which is one of the youngest objects having a candidate transiting planet. The da…
