The researchers weren't necessarily looking for this neutron star. Rather, it was happenstance as they searched for gravitational waves."At Green Bank, we're trying to detect gravitational waves from pulsars," said Maura McLaughlin, study author and Eberly Distinguished Professor of physics and astronomy at West Virginia University. "In order to do that, we need to observe lots of millisecond pulsars, which are rapidly rotating neutron stars. This is not a gravitational wave detection paper but one of many important results which have arisen from our observations."They were able to measure its mass because of a white dwarf companion star that warped the space around both stars. This warping acted as a way to accelerate the pulsar's pulses through space. They could learn the mass of the white dwarf and neutron star this way through the "Shapiro Delay.""Neutron stars are as mysterious as they are fascinating," said Thankful Cromartie, a graduate student at the University of Virginia and Grote Reber pre-doctoral fellow at the National Radio Astronomy Observatory in Charlottesville, Virginia. "These city-sized objects are essentially ginormous atomic nuclei. They are so massive that their interiors take on weird properties. Finding the maximum mass that physics and nature will allow can teach us a great deal about this otherwise inaccessible realm in astrophysics."Due to their mysterious nature, astronomers still want to answer more questions about neutron stars and this unique one could help them. They want to know if crushed neutrons become a type of "superfluid," what the breakdown looks like and where the actual tipping point lies when gravity takes over."The orientation of this binary star system created a fantastic cosmic laboratory," said Scott Ransom, study co-author and an astronomer at the National Radio Astronomy Observatory. "Neutron stars have this tipping point where their interior densities get so extreme that the force of gravity overwhelms even the ability of neutrons to resist further collapse. Each 'most massive' neutron star we find brings us closer to identifying that tipping point and helping us to understand the physics of matter at these mind-boggling densities." 2221

The time-of-use plan does away with the new state-mandated high-usage charge, which more than 80,000 San Diegans hit over a record-hot summer. That led to bills of 0 or more. Scott Crider, SDG&E's vice president of customer services, said he understands 4 p.m. to 9 p.m. is the time people cook dinner, turn on lights and run their air-conditioners. But he said the utility is encouraging residents to conserve when demand on the grid is highest. "What we're really asking our customers to really think about energy just a little bit differently and see if they can make some minor shifts of major appliances, for instance, instead of running your dishwasher at 7 p.m., can you set it on a time to run at 9 p.m. when electricity is cheaper," he said. The price difference between times of use are minimal during the winter. But that changes in the summer, when prices from 4 p.m. to 9 p.m. for most users will be nearly triple the most affordable hours. 961
