Using 14 years of high resolution near-infrared imaging, radio observations of molecular gas, and a hydrodynamic simulation the authors show that spiral arms seen in the protoplanetary disk around HD 100453 A are caused by its M-dwarf companion.
Using simulations, the author explores the possibility of observing seasonal changes on warm Jupiters with JWST.
What created the strong CIV absorption near this Lyman Alpha Emitter?
How do we measure the mass of our own galaxy? Today’s authors use simulations to compare (and improve) several methods.
How does habitability vary on a galactic scale?
Cool, hazy exoplanets might look a lot like Saturn’s moon Titan. Today’s post explores the possible atmospheres of exo-Titans around a variety of host stars.
