Debris disks are tenuous, dust-dominated disks commonly observed around stars over a
wide range of ages. Those around main sequence stars are analogous to the Solar System's …

Over the past three decades, we have witnessed one of the great revolutions in our
understanding of the cosmos—the dawn of the Exoplanet Era. Where once we knew of just …

Here, we show that the~ 10-million-year-old β Pictoris system hosts a massive giant planet,
β Pictoris b, located 8 to 15 astronomical units from the star. This result confirms that gas …

Context. Since the discovery of its dusty disk in 1984, β Pictoris has become the prototype of
young early-type planetary systems, and there are now various indications that a massive …

Many stars are surrounded by disks of dusty debris formed in the collisions of asteroids,
comets, and dwarf planets, but is gas also released in such events? Observations at …

Optical spectroscopy is used to confirm membership for eight low-mass candidates in the
young Beta Pic moving group (BPMG) via their radial velocities, chromospheric activity and …

Spatially resolved scattered-light images of circumstellar debris in exoplanetary systems
constrain the physical properties and orbits of the dust particles in these systems. They also …

Abstract The Rossiter-McLaughlin (RM) effect is the distortion of stellar spectral lines that
occurs during eclipses or transits, due to stellar rotation. We assess the future prospects for …

We present velocity-resolved spectroastrometric imaging of the 4.7 μm rovibrational lines of
CO gas in protoplanetary disks using the CRIRES high-resolution infrared spectrometer on …

We present new optical coronagraphic data of Fomalhaut obtained with HST/STIS in 2010
and 2012. Fomalhaut b is recovered at both epochs to high significance. The observations …
