Abstract: We report the discovery in K2's Campaign 10 of a transiting terrestrial planet in an ultra-short-period orbit around an M3-dwarf. K2-137 b completes an orbit in only 4.3 h, the second shortest orbital period of any… read more here.

Abstract: We compute the binding energy and angular momentum of a test-particle at the last stable circular orbit on the equatorial plane around a general relativistic, fast rotating neutron star. We present simple formulas that accurately… read more here.
