either only tiny fractions of the sky or a very small range of timescales. The situation is improving with the development of the Low Frequency Array (LOFAR), the Long Wavelength Array, the Murchison Widefield Array, and ATA-42 (the Allen Telescope Array, configured with 42 radio-telescope dishes). As radio fields of view continue to increase and computing capability grows to allow wide-field, rapid-cadence, radio imaging, new surveys will uncover many more transient events of both known and unknown origin. These events have the potential to tell about particle acceleration, stellar magnetic fields and rotation, strong-field gravity, the interstellar and intergalactic media, the violent deaths of stars, and possibly physics beyond the standard model.
In summary, the time domain represents great discovery potential well matched to the timescales that are relevant for stellar phenomena during their lifetimes and their death throes. Astronomers look forward to the next decade as a period of renaissance for stellar astronomy as time information is added to the new advances in three-dimensional spatial resolution and the idealization of a star as a static, spherical object is put to bed.
