Clustering properties of intermediate and high-mass Young Stellar Objects
Miguel Vioque, Manuel Cavieres, Michelangelo Pantaleoni González +6
We have selected 337 intermediate and high-mass YSOs ( to M) well-characterised with spectroscopy. By means of the clustering algorithm HDBSCAN, we study their…
Measuring the Dust Masses of Protoplanetary Disks in Lupus with ALMA: Evidence that Disks can be Optically Thick at 3 mm
Z. Xin, C. C. Espaillat, A. M. Rilinger +2
Accurate disk mass measurements are necessary to constrain disk evolution and the timescale of planet formation, but such measurements are difficult to make and are very dependent…
Determining Dust Properties in Protoplanetary Disks: SED-derived Masses and Settling With ALMA
Anneliese Rilinger, Catherine Espaillat, Zihua Xin +3
We present spectral energy distribution (SED) modeling of 338 disks around T Tauri stars from eleven star-forming regions, ranging from 0.5 to 10 Myr old. The disk masses we…
Gaia EDR3 comparative study of protoplanetary disk fractions in young stellar clusters
I. Mendigutía, E. Solano, M. Vioque +4
(Abridged) The lifetime of protoplanetary disks around young stars limits the timescale when planets form. A disk dissipation timescale < 10 Myr was inferred from surveys providing…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): A Panchromatic View of DO Tau's Complex Kilo-au Environment
Jane Huang, Christian Ginski, Myriam Benisty +20
While protoplanetary disks are often treated as isolated systems in planet formation models, observations increasingly suggest that vigorous interactions between Class II disks and…
A highly settled disk around Oph 163131
M. Villenave, K. R. Stapelfeldt, G. Duchene +10
High dust density in the midplane of protoplanetary disks is favorable for efficient grain growth and can allow fast formation of planetesimals and planets, before disks dissipate.…
HS observations in young stellar disks in Taurus
P. Rivière-Marichalar, A. Fuente, R. Le Gal +7
Context. Studying gas chemistry in protoplanetary disks is key to understanding the process of planet formation. Sulfur chemistry in particular is poorly understood in interstellar…
Probing protoplanetary disk evolution in the Chamaeleon II region
M. Villenave, F. Menard, W. R. F. Dent +13
Context. Characterizing the evolution of protoplanetary disks is necessary to improve our understanding of planet formation. Constraints on both dust and gas are needed to determin…
An ALMA Survey of Protoplanetary Disks in Lynds 1641
Sierra L. Grant, Catherine C. Espaillat, John Wendeborn +8
We present ALMA observations of 101 protoplanetary disks within the star-forming region Lynds 1641 in the Orion Molecular Cloud A. Our observations include 1.33 mm continuum emissi…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): A close low mass companion to ET Cha
C. Ginski, F. Ménard, Ch. Rab +25
To understand the formation of planetary systems, one needs to understand the initial conditions of planet formation, i.e. the young gas-rich planet forming disks. Spatially resolv…
Multiple rings in the transitional disk of GM Aurigae revealed by VLA and ALMA
Enrique Macias, Catherine C. Espaillat, Alvaro Ribas +6
Our understanding of protoplanetary disks is rapidly departing from the classical view of a smooth, axisymmetric disk. This is in part thanks to the high angular resolution that (s…
Long-lived protoplanetary disks in multiple systems: the VLA view of HD 98800
Álvaro Ribas, Enrique Macías, Catherine C. Espaillat +1
The conditions and evolution of protoplanetary disks in multiple systems can be considerably different from those around single stars, which may have important consequences for pla…
Far-infrared to millimeter data of protoplanetary disks: dust growth in the Taurus, Ophiuchus, and Chamaeleon I star-forming regions
Álvaro Ribas, Catherine C. Espaillat, Enrique Macías +7
Far-infrared and (sub)millimeter fluxes can be used to study dust in protoplanetary disks, the building blocks of planets. Here, we combine observations from the Herschel Space Obs…
An Incipient Debris Disk in the Chamaeleon I Cloud
C. C. Espaillat, Á. Ribas, M. K. McClure +5
The point at which a protoplanetary disk becomes a debris disk is difficult to identify. To better understand this, here we study the 40~AU separation binary T~54 in the Cham…
Constraining the properties of transitional disks in Chamaeleon I with Herschel
Á. Ribas, H. Bouy, B. Merín +4
Transitional disks are protoplanetary disks with opacity gaps/cavities in their dust distribution, a feature that may be linked to planet formation. We perform Bayesian modeling of…
X-ray deficiency on strong accreting T Tauri stars - Comparing Orion with Taurus
Ignacio Bustamante, Bruno Merín, Hervé Bouy +3
Depending on whether a T Tauri star accretes material from its circumstellar disk or not, different X-ray emission properties can be found. The accretion shocks produce cool heatin…
Herschel-PACS observations of discs in the Eta Chamaeleontis association
P. Riviere-Marichalar, P. Elliott, I. Rebollido +6
Protoplanetary discs are the birthplace for planets. Studying protoplanetary discs is the key to constraining theories of planet formation. By observing dust and gas in association…
Protoplanetary disk lifetimes vs stellar mass and possible implications for giant planet populations
Álvaro Ribas, Hervé Bouy, Bruno Merín
We study the dependence of protoplanetary disk evolution on stellar mass using a large sample of young stellar objects in nearby young star-forming regions. We update the protoplan…
Identification of new transitional disk candidates in Lupus with Herschel
I. Bustamante, B. Merín, Á. Ribas +4
New data from the Herschel Space Observatory are broadening our understanding of the physics and evolution of the outer regions of protoplanetary disks in star forming regions. In…
Messier 35 (NGC2168) DANCe I. Membership, proper motions and multi-wavelength photometry
H. Bouy, E. Bertin, D. Barrado +7
We aim at identifying the cluster's members by deriving membership probabilities for the sources within 1 degree of the cluster's center, going further away than equivalent previou…
Herschel/PACS photometry of transiting-planet host stars with candidate warm debris disks
Bruno Merín, David R. Ardila, Álvaro Ribas +4
Dust in debris disks is produced by colliding or evaporating planetesimals, remnants of the planet formation process. Warm dust disks, known by their emission at < 24 micron, are r…
