Megan Ansdell,Jonathan Williams,N. van der Marel,John M. Carpenter,G. Guidi,Michiel R. Hogerheijde,G. S. Mathews,Carlo F. Manara,Anna Miotello,A. Natta,A. Natta,Isa Oliveira,Marco Tazzari,Leonardo Testi,Leonardo Testi,E. F. van Dishoeck,S. E. van Terwisga +16 more
TL;DR: In this paper, the Atacama Large Millimeter/Submillimeter Array (ALMA) was used to survey 89 protoplanetary disks around stars with M∗ > 0.1 M in the young (1-3 Myr), nearby (150-200 pc) Lupus complex.
Journal ArticleDOI
Evidence for a correlation between mass accretion rates onto young stars and the mass of their protoplanetary disks
Carlo F. Manara,Giovanni P. Rosotti,Leonardo Testi,Leonardo Testi,A. Natta,A. Natta,Juan M. Alcalá,Jonathan P. Williams,Megan Ansdell,Anna Miotello,N. van der Marel,N. van der Marel,Marco Tazzari,John M. Carpenter,G. Guidi,G. S. Mathews,Isa Oliveira,Timo Prusti,E. F. van Dishoeck +18 more
TL;DR: In this article, the photospheric parameters, mass accretion rate, and disk mass for an essentially complete sample of young stars with disks in the Lupus clouds were determined using the results of surveys conducted with VLT/X-Shooter and ALMA.
Journal ArticleDOI
Observations of Herbig Ae/Be stars with Herschel/PACS - The atomic and molecular contents of their protoplanetary discs
Gwendolyn Meeus,Benjamin Montesinos,I. Mendigutía,Inga Kamp,Wing-Fai Thi,Carlos Eiroa,Carol A. Grady,G. S. Mathews,Göran Sandell,C. Martin-Zaidi,Sean D. Brittain,William R. F. Dent,Christian D. Howard,Francois Menard,Christophe Pinte,Aki Roberge,Bart Vandenbussche,Jonathan Williams +17 more
TL;DR: In this article, the authors observed a sample of 20 representative Herbig Ae/Be stars and 5 A-type debris discs with PACS onboard Herschel, as part of the GAS in Protoplanetary Systems (GASPS) project.
Journal ArticleDOI
ALMA imaging of the CO snowline of the HD 163296 disk with DCO
G. S. Mathews,P. D. Klaassen,Attila Juhasz,Daniel Harsono,Daniel Harsono,E. Chapillon,E. F. van Dishoeck,Daniel Espada,I. de Gregorio-Monsalvo,A. S. Hales,Michiel R. Hogerheijde,Joseph C. Mottram,Mark G. Rawlings,Satoko Takahashi,Leonardo Testi,Leonardo Testi +15 more
TL;DR: In this paper, the Atacama Large Millimeter/submillimeter Array (ALMA) data was used to directly resolve the CO snowline and determine the temperature boundaries of the region of DCO+ emission in the HD 163296 disk.
Journal ArticleDOI
An Icy Kuiper-Belt Around the Young Solar-Type Star HD 181327
J. Lebreton,Jean-Charles Augereau,W. F. Thi,Aki Roberge,J. Donaldson,Glenn Schneider,Sarah T. Maddison,Francois Menard,Pablo Riviere-Marichalar,G. S. Mathews,Inga Kamp,Christophe Pinte,William R. F. Dent,David Barrado,Gaspard Duchêne,Jean-François Gonzalez,Carol A. Grady,Gwendolyn Meeus,Eric Pantin,Jonathan Williams,Peter Woitke,Peter Woitke +21 more
TL;DR: In this paper, the spectral energy distribution (SED) of HD 181327 has been studied in detail, and it has been shown that the gas-to-dust ratio is at most 0.17 solar mass.
