Upper Limits On CN From Exocomets Transiting Beta Pictoris
The young (23 Myr) nearby (19.4 pc) star β Pictoris hosts an edge-on debris disk with two gas giant exoplanets in orbit around it. Many transient absorption features have been […]

Abundances Of Refractory Ions In Beta Pictoris Exocomets
Beta Pic is a young, A5V star, known for harbouring a large number of exocomets, which frequently transit the star and produce absorption signatures.

A Potential Exomoon From The Predicted Planet Obliquity Of β Pictoris b
Planet obliquity is the alignment or misalignment of a planet spin axis relative to its orbit normal. In a multiplanet system, this obliquity is a valuable signature of planet formation […]

Classifications For Exoplanet and Exoplanetary Systems
When a star is described as a spectral class G2V, we know its approximate mass, temperature, age, and size. At more than 5,700 exoplanets discovered, it is a natural developmental […]
