We report the detection of radio QPOs with structure changes using the Very Long Baseline Array (VLBA) at 43 GHz. We found conspicuous patterned changes of the structure with P = 16.8, 22.2, 31.4,&56.4 min, roughly in a 3 : 4 : 6 : 10 ratio. The first two periods show a rotating one-arm structure, while the P = 31.4 min shows a rotating 3-arm structure, as if viewed edge-on. At the central 50μa...
In the presented work CaCO3 powders were produced by controlled fast precipitation through gaseous carbon dioxide absorption in calcium hydroxide slurry. This multiphase reaction was conducted in a modified prototypical rotating disk reactor (RDR). The concept is based on continuous formation of thin liquid films at a surface of rotating discs where the mass transfer proceeds in diffusion-conve...
This is the first paper about the fragmentation and mass outflow in the molecular cloud by using three-dimensional MHD nested-grid simulations. The binary star formation process is studied paying particular attention to the fragmentation of a rotating magnetized molecular cloud. We assume an isothermal rotating and magnetized cylindrical cloud in hydrostatic balance. Non-axisymmetric as well as...
Observations were made that falsify planetary formation via proto-planetary disk. An alternative model is proposed. Observations that Falsify the Proto-planetary Disk/Nebular Hypothesis Model: 1. Older stars are still mislabeled by mainstream as planets/exo-planets. [1] They orbit the opposite direction their host star is rotating. [2] The backwards orbits completely falsifies any notion of a c...
