Testing Molecular-Cloud Fragmentation Theories: Self-Consistent Analysis of OH Zeeman Observations
The ambipolar-diffusion theory of star formation predicts the formation of fragments in molecular clouds with mass-to-flux ratios greater than that of the parent-cloud envelope. By contrast, scenarios of turbulence-induced fragmentation do not yield such a robust prediction. Based on this property, Crutcher et al. (2009) proposed an observational test that could potentially discriminate between...
متن کاملZeeman splitting in OH megamasers
We detected significant Zeeman splitting in the 1667MHz OH megamaser emission from four ultraluminous galaxies. These detections, in addition to being the first extragalactic detection of the Zeeman effect in an emission line, suggest that OH megamasers are excellent extragalactic magnetometers.
متن کاملRecent Oh Zeeman Observations: Do They Really Contradict the Ambipolar-diffusion Theory of Star Formation?
Until recently, many of the dozens of quantitative predictions of the ambipolar-diffusion theory of gravitational fragmentation (or core formation) of molecular clouds have been confirmed by observations and, just as importantly, no prediction has been contradicted by any observation. A recent paper, however, claims that measurements of the variation of the mass-to-flux ratio from envelopes to ...
متن کاملExtragalactic Zeeman Detections in Oh Megamasers
We have measured the Zeeman splitting of OH megamaser emission at 1667 MHz from five (ultra)luminous infrared galaxies ([U]LIRGs) using the 305 m Arecibo telescope and the 100 m Green Bank Telescope. Five of eight targeted galaxies show significant Zeeman-splitting detections, with 14 individual masing components detected and line-of-sight magnetic field strengths ranging from ≃ 0.5 − 18 mG. Th...
متن کاملZeeman Observations of W Sgr*
A new precise method for measuring magnetic fields on Zeeman plates of the southern cepheid W Sgr is reviewed. Ten plates over the 7_6 period of pulsation show two extrema in the measured values of the effective magnetic field. The method has a precision of ±0.4_ in the Zeeman shift corresponding to ±50 gauss (g). A negative "spike" of -220g occurred at the time of arrival of the compressional ...
