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…
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…
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…
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 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…
