A Uniform Analysis of Debris Disks with the Gemini Planet Imager II: Constraints on Dust Density Distribution Using Empirically-Informed Scattering Phase Functions
Justin Hom, Jennifer Patience, Christine H. Chen +40
Spatially-resolved images of debris disks are necessary to determine disk morphological properties and the scattering phase function (SPF) which quantifies the brightness of scatte…
Multiple Rings of Millimeter Dust Emission in the HD 15115 Debris Disk
Meredith A. MacGregor, Alycia J. Weinberger, Erika R. Nesvold +8
We present observations of the HD 15115 debris disk from ALMA at 1.3 mm that capture this intriguing system with the highest resolution ( or AU) at mil…
ALMA Detection of Extended Millimeter Halos in the HD 32297 and HD 61005 Debris Disks
Meredith A. MacGregor, Alycia J. Weinberger, A. Meredith Hughes +7
We present ALMA 1.3 mm (230 GHz) observations of the HD 32297 and HD 61005 debris disks, two of the most iconic debris disks due to their dramatic swept-back wings seen in scattere…
New Parallaxes for the Upper Scorpius OB Association
Jessica Donaldson, Alycia Weinberger, Jonathan Gagné +2
Upper Scorpius is a subgroup of the nearest OB association, Scorpius--Centaurus. Its young age makes it an important association to study star and planet formation. We present para…
Optical Coronagraphic Spectroscopy of AU Mic: Evidence of Time Variable Colors?
Jamie R. Lomax, John P. Wisniewski, Aki Roberge +4
We present coronagraphic long slit spectra of AU Mic's debris disk taken with the STIS instrument aboard the Hubble Space Telescope (HST). Our spectra are the first spatially resol…
BANYAN. IX. The Initial Mass Function and Planetary-Mass Object Space Density of the TW Hya Association
Jonathan Gagné, Jacqueline K. Faherty, Eric E. Mamajek +15
A determination of the initial mass function (IMF) of the current, incomplete census of the 10 Myr-old TW Hya association (TWA) is presented. This census is built from a literature…
New Parallaxes and a Convergence Analysis for the TW Hya Association
Jessica K. Donaldson, Alycia J. Weinberger, Jonathan Gagné +3
The TW Hya Association (TWA) is a nearby stellar association with an age of 5-10 Myr. This is an important age for studying the late stages of star and planet formation. We…
Exocometary gas in the HD 181327 debris ring
S. Marino, L. Matra, C. Stark +14
An increasing number of observations have shown that gaseous debris discs are not an exception. However, until now we only knew of cases around A stars. Here we present the first d…
Gas and dust in the Beta Pictoris Moving Group as seen by the Herschel Space Observatory
P. Riviere-Marichalar, D. Barrado, B. Montesinos +11
Context. Debris discs are thought to be formed through the collisional grinding of planetesimals, and can be considered as the outcome of planet formation. Understanding the proper…
Dust May Be More Rare Than Expected in Metal Poor Galaxies
David B. Fisher, Alberto D. Bolatto, Rodrigo Herrera-Camus +7
'Normal' galaxies observed at z>6, when the Universe was <1 billion years old, thus far show no evidence of the cold dust that accompanies star formation in the local Universe, whe…
Gas and dust in the TW Hydrae Association as seen by the Herschel Space Observatory
P. Riviere-Marichalar, C. Pinte, D. Barrado +15
Context. Circumstellar discs are the places where planets form, therefore knowledge of their evolution is crucial for our understanding of planet formation. The Herschel Space Obse…
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…
Modeling the HD32297 Debris Disk with Far-IR Herschel Data
J. K. Donaldson, J. Lebreton, A. Roberge +2
HD32297 is a young A-star (~30 Myr) 112 pc away with a bright edge-on debris disk that has been resolved in scattered light. We observed the HD32297 debris disk in the far-infrared…
Herschel Observations of Gas and Dust in the Unusual 49 Ceti Debris Disk
A. Roberge, I. Kamp, B. Montesinos +12
We present far-IR/sub-mm imaging and spectroscopy of 49 Ceti, an unusual circumstellar disk around a nearby young A1V star. The system is famous for showing the dust properties of…
Herschel PACS Observations and Modeling of Debris Disks in the Tucana-Horologium Association
J. K. Donaldson, A. Roberge, C. H. Chen +9
We present Herschel PACS photometry of seventeen B- to M-type stars in the 30 Myr-old Tucana-Horologium Association. This work is part of the Herschel Open Time Key Programme "Gas…
Dust-to-Gas Ratio in the Extremely Metal Poor Galaxy I ZW 18
Rodrigo Herrera-Camus, David B. Fisher, Alberto D. Bolatto +7
The blue compact dwarf galaxy I Zw 18 is one of the most metal poor systems known in the local Universe (12 + log(O/H) 7.17). In this work we study I Zw 18 using data from {\it…
