Transit observations can yield a lot of information about exoplanets. If a transiting exoplanet encounters stellar wind, the bow shock created can show up in the transit light curves. In this paper, the authors investigate how the stellar wind of a star can shape the light curves we observe.
Astronomers love to ignore magnetic fields. But they may strongly affect the pattern of atmospheric circulation in hot Jupiters.
The authors of this article observe a sudden slowing in the rotation rate of a known magnetar. Although hundreds of glitches (a sudden increase in rotation rate) have been observed in radio pulsars and magnetars, this is the first direct evidence for an anti-glitch.
The undergraduate research series has been revived! This month’s post features research on neutrinos from failed supernovae and compact-object mergers, as well as research on magnetic fields in the intracluster medium.
The authors present the discovery of a new hot carbon-atmosphere white dwarf with a strong magnetic field. This discovery might help illuminate the origins of a recently found class of white dwarfs.
Boss & Keiser examine how magnetic fields with varying initial conditions affect star formation.
Voids in the cosmic web are observed to be contain large-scale magnetic fields … but it’s unclear how this happens. In this paper, the authors suggest two possible explanations.
This paper delves into some of the physical properties of early M dwarfs (M0-M4.5), focusing on chromospheric/magnetic activity and rotation. The authors present a catalog of activity and rotation for 334 early M dwarfs.
In this article the authors simulate the collapse of a magnetized, turbulent molecular cloud core to see if rotationally supported discs can form around central protostars.
Young massive stars have a variety of different rotation rates, but what sets these initial speeds? In this paper, the authors investigate whether magnetic fields could be the answer.
