![Distance versus time distributions for the 49 encounters with β Pic that have an empirical probability of at least 95% of occurring within 2 pc. The coloured points indicate the rescaled Mahalanobis distances (ensuring a common colour scale for all stars) derived from the encounter parameters. Points above the 95th percentile of this metric are shown in grey. The black bars represent the 95% confidence intervals in time and distance, obtained from the 2.5th and 97.5th percentiles of the corresponding marginal distributions for the further encounters and using the 95th percentile to define the one-tailed distance interval for the closest ones. The central points are the 50th percentiles. The critical radius of 2 pc is indicated by the red horizontal line. The centres of mass of binary systems, listed in table 4, are marked at the pair [t50, d50] corresponding to that star. -- astro-ph.SR](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/10/A-Kinematic-History-Of-Stellar.png?resize=1200%2C719&ssl=1)

Multi-modal Atmospheric Characterization Of beta Pictoris b: Adding High-resolution Continuum Spectra From GRAVITY
We present the first VLTI/GRAVITY observations at Rλ∼4000 of β Pic b. These four high S/N (∼20) K-band spectra conserve both the pseudo-continuum and molecular absorption patterns.

Exocomets of Beta Pictoris I: Exocomet destruction, sodium and disk line variability in 17 years of HARPS observations
The young β Pictoris system has been monitored with high-resolution optical spectrographs for decades. These observations have revealed strongly variable absorption in the Ca II H\&K lines attributed to in-falling […]

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.
