PSR B1509-58 - X-rays from Chandra are gold; Infrared from WISE in red, green and blue/max. A pulsar (from pulse and -ar as in quasar) is a highly magnetized, rotating neutron star or white dwarf, that emits a beam of electromagnetic radiation. This radiation can be observed only when the beam of emission is pointing toward Earth (much like the way a lighthouse can be seen only when the light is pointed in the direction of an observer), and is responsible for the pulsed appearance of emission.
SWAR. by David Courtney. Swar are nothing more than the seven notes of the Indian musical scale. Swar is also called sur . At a fundamental level they are similar to the solfa of Western music. These are shown in the table below. Two of these swar are noteworthy in that they are immutably fixed. These two notes are shadj (Sa) and pancham (Pa) and are referred to as achala swar . These two swar form the tonal foundation for all the Indian classical music.
