Protoplanetary nebulae as a research area focuses on the short-lived transitional phase of low- to intermediate-mass stellar evolution between the asymptotic giant branch and planetary nebula stages, emphasizing the physics of mass loss, circumstellar morphology, and dust-gas chemistry. Studies investigate the shaping mechanisms that produce bipolar and multipolar structures, including fast collimated winds, magnetic fields, and binary interactions, as well as radiative transfer, shock excitation, and molecular emission processes. This field integrates high-resolution imaging, spectroscopic diagnostics, and hydrodynamical and magnetohydrodynamical simulations to constrain evolutionary timescales, envelope kinematics, and the feedback of late-stage stellar evolution on the interstellar medium.
Astronomers have used radio observations from the Atacama Large Millimeter/submillimeter Array (ALMA) to catch a dying star in the middle of a dramatic transformation, and the data show a ring that records its final outburst. ...
Science in the modern era is increasingly reliant on enormous datasets and automated analysis. In astronomy, the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST)—a ten-year survey covering the entire southern ...
