The presence of off-plane Ca II ions in the Beta Pictoris disk, and the non-detection of off-plane Na I atoms, can be explained as a consequence of the evaporation process of Falling Evaporating Bodies (FEBs). In the star-grazing regime, the FEBs are subject to inclination oscillations up to 30 - 40 degrees that causes most metallic species released by sublimation to move off plane The ions are be stopped at about 100 AU from the star. We show that collisions with a neutral medium can stop the… Expand

Fe I in the β Pictoris circumstellar gas disk: I. Physical properties of the neutral iron gas⋆
The young planetary system β  Pictoris is surrounded by a circumstellar disk of dust and gas. Because both dust and gas have a lifetime shorter than the system age, they need to be replenishedExpand
Herschel/HIFI observations of ionised carbon in the β Pictoris debris disk
Context. The dusty debris disk around the 20 Myr old main-sequence A-star Pictoris is known to contain gas. Evidence points towards a secondary origin of the gas as opposed to being a direct remnantExpand
VLT imaging of the beta Pictoris gas disk
Context. Circumstellar debris disks older than a few Myr should be largely devoid of primordial gas remaining from the protoplanetary disk phase. Tracing the origin of observed atomic gas inExpand
The Dust and Gas Around β Pictoris
We have obtained Spitzer IRS 5.5-35 ?m spectroscopy of the debris disk around ? Pictoris. In addition to the 10 ?m silicate emission feature originally observed from the ground, we also detect theExpand
Exocomets in the circumstellar gas disk of HD 172555
The source HD 172555 is a young A7V star surrounded by a debris disk with a gaseous component. Here, we present the detection of variable absorption features detected simultaneously in the Ca II KExpand
β Pictoris: observations of the Ca ii H&K absorptions in 1997 and 1998
We present spectroscopy with resolution R ∼ 33 000 of the circumstellar Ca ii H&K absorptions in the star β Pictoris during 1997 and 1998. From 1997 April onwards, both lines were observedExpand
Orbital characterization of the β Pictoris b giant planet
In June 2010, we confirmed the existence of a giant planet in the disk of the young star Beta Pictoris, located between 8 AU and 15 AU from the star. This young planet offers the rare opportunity toExpand
Gas has been detected in a number of debris disk systems. This gas may have arisen from grain sublimation or grain photodesorption. It interacts with the surrounding dust grains through a number ofExpand
An independent determination of Fomalhaut b’s orbit and the dynamical effects on the outer dust belt
The nearby star Fomalhaut harbours a cold, moderately eccentric dust belt with a sharp inner edge near 133 au. A low-mass, common proper motion companion (Fom b), was discovered near the inner edgeExpand
Resolved Gas Interior to the Dust Rings of the HD 141569 Disk
The disk around HD 141569 is one of a handful of systems whose weak infrared emission is consistent with a debris disk, but still has a significant reservoir of gas. Here we report spatially resolvedExpand


Falling evaporating bodies in the β Pictoris system - Resonance refilling and long term duration of the phenomenon
The transient spectral absorption events that have been monitored for years towards the star Pictoris have been interpreted as resulting from the transit across the line of sight of evaporating,Expand
Braking the Gas in the β Pictoris Disk
The star β Pictoris hosts the best studied circumstellar disk to date. Nonetheless, a long-standing puzzle has been around since the detection of metallic gas in the disk: radiation pressure from theExpand
