The hot Jupiter WASP-12b has been found to be on a decaying 1.09-day orbit. mean density of the planet inferred from transit and radial-velocity data is near its Roche limit; just how depends planet's uncertain internal structure. There also spectroscopic evidence mass loss. We accurately calculate assumption synchronously rotating $n=1$ polytrope, find this only $15-20\%$ below observational e...

In this work, twelve analogues of piperidine alkaloids (-)-cassine and (-)-spectaline were synthesized, as well the racemic forms these natural products. The compounds evaluated for their inhibition electric eel acetylcholinesterase (AChEee) human butyrylcholinesterase (BChEhu) by on-flow mass-spectrometry-based dual-enzyme assay, mechanisms most potent also determined. Our results showed a pre...

This study aims to examine the formulative policy of reversing provision proof crime graft corruption in ius constitutum or positive law Indonesia and constituendum future Indonesia. research is a normative legal research. The results show that for proving regulated Article 12B Law No. 20 2001 concerning Amendments Number 31 1999 Eradication Corruption Crimes does not yet reflect justice certai...

In the standard theory of equilibrium tides, hydrodynamic turbulence is considered. this paper we study effect magnetic fields on tides. We find that turbulent Ohmic dissipation associated with a tidal flow much stronger than viscous such field can greatly speed up evolution binary system. then apply to three systems: orbital migration 51 Pegasi b, decay WASP-12b, and circularization close star...

We report the discovery of planet Kepler-12b (KOI-20), which at 1.695± 0.030 RJ is among the handful of planets with super-inflated radii above 1.65 RJ. Orbiting its slightly evolved G0 host with a 4.438-day period, this 0.431± 0.041 MJ planet is the least-irradiated within this largest-planet-radius group, which has important implications for planetary physics. The planet’s inflated radius and...
