CO Ro-vibrational Spectroscopy of AB Aurigae -- A Potential Point Source is Present
Janus Kozdon, Jeffrey Fung, Sean D. Brittain +4
The Herbig Ae star AB Aurigae hosts a vast, low-inclination protoplanetary disk that exhibits a plethora of substructures, including the protoplanet candidate AB Aur b. We present…
Evolution of the Accretion Rate of Young Intermediate Mass Stars: Implications for Disk Evolution and Planet Formation
Sean D. Brittain, Joshua W. Kern, Gwendolyn Meeus +1
This work presents a study of the evolution of the stellar accretion rates of pre-main-sequence intermediate-mass stars. We compare the accretion rate of the younger intermediate-m…
Vertical Structure of Gas and Dust in Four Debris Disks
Kadin Worthen, Christine H. Chen, Sean Brittain +8
We present high-spectral resolution M-band spectra from iSHELL on NASA's Infrared Telescope Facility (IRTF) along the line of sight to the debris disk host star HD 32297. We also p…
Full L- and M-band high resolution spectroscopy of the S CrA binary disks with VLT-CRIRES+
Sierra L. Grant, Giulio Bettoni, Andrea Banzatti +7
The Cryogenic IR echelle Spectrometer (CRIRES) instrument at the Very Large Telescope (VLT) was in operation from 2006 to 2014. Great strides in characterizing the inner regions of…
The -- relationship for Herbig Ae/Be stars: a lifetime problem for disks with low masses?
Sierra L. Grant, Lucas M. Stapper, Michiel R. Hogerheijde +3
The accretion of material from protoplanetary disks onto their central stars is a fundamental process in the evolution of these systems and a key diagnostic in constraining the dis…
Probing the gaseous disk of T Tau N with CN 5-4 lines
L. Podio, I. Kamp, C. Codella +12
We present spectrally resolved Herschel/HIFI observations of the young multiple system T Tau in atomic and molecular lines. While CO, H2O, [C II], and SO lines trace the envelope a…
Accretion variability of Herbig Ae/Be stars observed by X-Shooter. HD 31648 and HD 163296
I. Mendigutía, S. D. Brittain, C. Eiroa +6
This work presents X-Shooter/VLT spectra of the prototypical, isolated Herbig Ae stars HD 31648 (MWC 480) and HD 163296 over five epochs separated by timescales ranging from days t…
GASPS - a Herschel survey of gas and dust in Protoplanetary Disks: Summary and Initial Statistics
W. R. F. Dent, W. F. Thi, I. Kamp +47
GASPS is a far-infrared line and continuum survey of protoplanetary and young debris disks using PACS on the Herschel Space Observatory. The survey includes [OI] at 63 microns, as…
Herschel/PACS observations of young sources in Taurus: the far-infrared counterpart of optical jets
L. Podio, I. Kamp, D. Flower +8
Observations of the atomic and molecular line emission associated with jets and outflows emitted by young stellar objects can be used to trace the various evolutionary stages they…
GASPS observations of Herbig Ae/Be stars with PACS/Herschel. The atomic and molecular content of their protoplanetary discs
G. Meeus, B. Montesinos, I. Mendigutia +3
We observed a sample of 20 representative Herbig Ae/Be stars and five A-type debris discs with PACS onboard of Herschel. The observations were done in spectroscopic mode, and cover…
Detection of CH+ emission from the disc around HD100546
W. -F. Thi, F. Ménard, G. Meeus +13
Despite its importance in the thermal-balance of the gas and in the determination of primeval planetary atmospheres, the chemistry in protoplanetary discs remains poorly constraine…
Water depletion in the disk atmosphere of Herbig AeBe stars
D. Fedele, I. Pascucci, S. Brittain +5
We present high resolution (R = 100,000) L-band spectroscopy of 11 Herbig AeBe stars with circumstellar disks. The observations were obtained with the VLT/CRIRES to detect hot wate…
The unusual protoplanetary disk around the T Tauri star ET Cha
P. Woitke, B. Riaz, G. Duchene +15
We present new continuum and line observations, along with modelling, of the faint (6-8) Myr old T Tauri star ET Cha belonging to the eta Chamaeleontis cluster. We have acquired HE…
Gas in Protoplanetary Discs (GASPS) 1. First results
G. S. Mathews, W. R. F. Dent, J. P. Williams +50
Context - Circumstellar discs are ubiquitous around young stars, but rapidly dissipate their gas and dust on timescales of a few Myr. The Herschel space observatory allows for the…
