Plasma heating inside ICMEs by Alfvenic fluctuations dissipation

Kavli Affiliate: John W. Belcher | First 5 Authors: Hui Li, Chi Wang, Jiansen He, Lingqian Zhang, John D. Richardson | Summary: Nonlinear cascade of low-frequency Alfvenic fluctuations (AFs) is regarded as one candidate of the energy sources to heat plasma during the non-adiabatic expansion of interplanetary coronal mass ejections (ICMEs). However, AFs inside ICMEs […]

Mn-doping induced ferromagnetism and enhanced superconductivity in Bi_4-x Mn_x O_4 S_3 (0.075 < = x < = 0.15)

Kavli Affiliate: N. C. Yeh | First 5 Authors: Zhenjie Feng, Xunqing Yin, Yiming Cao, Xianglian Peng, Tian Gao | Summary: We demonstrate that Mn-doping in the layered sulfides Bi_4O_4S_3 leads to stable Bi_4-x Mn_x O_4 S_3 compounds that exhibit both long-range ferromagnetism and enhanced superconductivity for 0.075 < = x < = 0.15, with […]

Repetitive Patterns in Rapid Optical Variations in the Nearby Black-hole Binary V404 Cygni

Kavli Affiliate: Stuart L. Marshall | First 5 Authors: Mariko Kimura, Keisuke Isogai, Taichi Kato, Yoshihiro Ueda, Satoshi Nakahira | Summary: How black holes accrete surrounding matter is a fundamental, yet unsolved question in astrophysics. It is generally believed that matter is absorbed into black holes via accretion disks, the state of which depends primarily […]

Evidence for simultaneous jets and disk winds in luminous low-mass X-ray binaries

Kavli Affiliate: Norbert Schulz | First 5 Authors: Jeroen Homan, Joseph Neilsen, Jessamyn L. Allen, Deepto Chakrabarty, Rob Fender | Summary: Recent work on jets and disk winds in low-mass X-ray binaries (LMXBs) suggests that they are to a large extent mutually exclusive, with jets observed in spectrally hard states and disk winds observed in […]
