An analysis of coronal mass ejections during solar cycles 23 and 24 shows that the mass-loss rate of these events changes with the solar cycle, with certain latitudinal dependencies also present.

A comparison of several simulations of thin black hole accretion disk models finds general agreement, with features in common such as increasing inverse Compton scattering with increasing black hole spin.

Though many pulsars have been found in globular clusters, no pulsars have been discovered in open clusters; a new radio search may have changed that, though the pulsar candidate has not yet been confirmed.

With several spacecraft having flown by or taken up temporary residence in the Jupiter system over the past few decades, researchers can now study changes in volcanism on Jupiter’s moon Io.

Using Bayesian statistical methods, researchers determine the number of “perfect” and imperfect observations necessary to draw conclusions about the frequency of habitable planets in the universe.

Detecting neutrinos from supergiant stars in the carbon-burning phase would provide valuable insights into the details of stellar evolution, but detecting these neutrinos is challenging with current technology.
