Observations of molecular clouds show that dense filaments are the sites of present-day star formation, and it is thus necessary to understand the filament formation process because the filament is an initial condition in a star formation process. Theoretical studies suggest that shock waves in molecular clouds trigger filament formation. Several different mechanisms have been proposed, and the formation mechanism of the observed star-forming filaments is expected to be clarified. In this book, the author performs a series of isothermal magnetohydrodynamics (MHD) simulations of filament formation and identifies the formation mechanisms. It is found that the dominant filament formation mode changes with the velocity of the shock waves that trigger the filament formation. The filament width plays an important role in determining the fragmentation scale by self-gravity, and observations show that the width 0.1 pc is universal. On the other hand, in theory the width of the supercritical filaments was considered to be narrowed by self-gravity. Recent studies suggest that massive filaments are bound by the slow shocks that are caused by accretion flows onto the filaments. Since the wavefront of such a slow shock is known to be unstable as a slow shock instability (SSI), the accretion ram pressure is expected to be converted into thermal/turbulent pressure across the shock front, which potentially maintains the width. In the scale of dense filaments, ambipolar diffusion (AD) suppresses the SSI at small scales. The influence of AD on SSI is investigated using two-dimensional MHD simulations, and the nonlinear evolution of the SSI with AD is found to drive turbulences. The book demonstrate the effect of SSI including AD onto the filament evolution. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5061 606 $aAstrophysics 606 $aPlasma astrophysics 606 $aPlasma waves 606 $aPlasma turbulence 606 $aAstrophysics 606 $aAstrophysical Plasma 606 $aWaves, instabilities and nonlinear plasma dynamics 606 $aTurbulence in plasmas 615 0$aAstrophysics. 615 0$aPlasma astrophysics. 615 0$aPlasma waves. 615 0$aPlasma turbulence. 615 14$aAstrophysics. 615 24$aAstrophysical Plasma. 615 24$aWaves, instabilities and nonlinear plasma dynamics. 615 24$aTurbulence in plasmas. 676 $a523.88 700 $aAbe$b Daisei$01846143 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910887882503321 996 $aFormation and Evolution of Star-Forming Filaments in Molecular Clouds$94430238 997 $aUNINA LEADER 02222oam 2200289z- 450 001 9910158922103321 005 20230906203136.0 010 $a1-925209-89-X 035 $a(CKB)3710000001011589 035 $a(BIP)052212720 035 $a(VLeBooks)9781925209891 035 $a(Exl-AI)993710000001011589 035 $a(EXLCZ)993710000001011589 100 $a20210505c2015uuuu -u- - 101 0 $aeng 200 $aWind Up the Windows We're Coming in to Land 210 $cVivid Publishing 215 $a1 online resource (220 p.) 330 8 $aFrom the beautiful pristine rivers and streams of New Zealand to the muddy brown waters of the Amazon, Dave Sharp lived his childhood dream of always wanting to travel. From being a local butcher in Takaka NZ to moving oil rigs across the ice in Canada he lived an intriguing and adventurous life. Held up at gunpoint, being entertained by a President's right hand man, dealing with buses that never ran on time...or even ran at all, bribing government officials and sharing rides with live chickens, the book tells it all. Read about the highs and lows he went through losing his mother at an early age followed not long after by losing his family home by fire, then jagging the best job in the world building ice bridges in the Yukon, this will whet your appetite....you won't want to put this book down. This small town boy whose carefree days in the 1950's and 60's were spent with friends down at the local creek or making mischief as a teenager with his home brew, Dave's early years had a huge bearing on the rest of his life. His father, HO, being his greatest rock throughout this time. Read about working an oil rig inside the Arctic circle, the tear gas gun in Central America, his lovely Mexican lady whose heart he broke and the movie star he became in Hong Kong. Throw in the odd opium den, pig pen toilet and drunken barman ......you'll soon get the picture. 606 $aAdventure travel$7Generated by AI 608 $aAutobiographies$7Generated by AI. 615 0$aAdventure travel 700 $aSharp$b Dave$01433434 906 $aBOOK 912 $a9910158922103321 996 $aWind Up The Windows We?re Coming In To Land$93581438 997 $aUNINA
