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.
There’s a strange sickle-shaped object in the Carina Nebula. The authors of this paper used observations at several different wavelengths to investigate the nature of this intriguing nebula, leading to some interesting discoveries and even more questions.
Recent data from IBEX has revealed that our decades-old model of the heliosphere is wrong: there is no bow shock ahead of the heliosphere in the ISM.
