Chemistry on solar system scales
Catherine Walsh, Maria Drozdovskaya, Dmitry Semenov +33
The initial chemical composition of planets, primitive bodies in our solar system, and exoplanets is ultimately set by their nascent protoplanetary disks. Yet observing key carbon-…
Planet forming disk populations and their connection to the environment
Thomas J. Haworth, Giovanni Rosotti, Carlo Manara +35
Existing sub-mm observatories such as ALMA have provided statistics on the planet-forming mass reservoirs within circumstellar disks around stars in stellar clusters out to distanc…
AB Aur, a Rosetta stone for studies of planet formation (II): HS detection and sulfur budget
Pablo Rivière-Marichalar, Asunción Fuente, Gisela Esplugues +7
The sulfur abundance is poorly known in most environments. Yet, deriving the sulfur abundance is key to understanding the evolution of the chemistry from molecular clouds to planet…
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…
A coplanar circumbinary protoplanetary disk in the TWA 3 triple M dwarf system
Ian Czekala, Álvaro Ribas, Nicolás Cuello +5
We present sensitive ALMA observations of TWA 3, a nearby, young (10 Myr) hierarchical system composed of three pre-main sequence M3--M4.5 stars. For the first time, we detec…
Binary-induced spiral arms inside the disc cavity of AB Aurigae
Pedro P. Poblete, Josh Calcino, Nicolás Cuello +5
In this work we demonstrate that the inner spiral structure observed in AB Aurigae can be created by a binary star orbiting inside the dust cavity. We find that a companion with a…
The Radial Distribution of Dust Particles in the HL Tau Disk from ALMA and VLA Observations
Carlos Carrasco-González, Anibal Sierra, Mario Flock +13
Understanding planet formation requires to discern how dust grows in protoplanetary disks. An important parameter to measure in disks is the maximum dust grain size present. This i…
Revealing the Star-Disk-Jet Connection in GM Aur using Multiwavelength Variability
C. C. Espaillat, E. Macias, J. Hernandez +1
Here we analyze the first simultaneous X-ray, ultraviolet, optical, infrared, and centimeter observations of a T Tauri star (TTS). We present three epochs of simultaneous Spitzer a…
Modeling the Protoplanetary Disks of Two Brown Dwarfs in the Taurus Molecular Cloud
Anneliese M. Rilinger, Catherine C. Espaillat, Enrique Macías
Measuring the properties of protoplanetary disks around brown dwarfs is central to understanding the formation of brown dwarfs and their planetary companions. We present modeling o…
An analytical model of radial dust trapping in protoplanetary disks
Anibal Sierra, Susana Lizano, Enrique Macías +3
We study dust concentration in axisymmetric gas rings in protoplanetary disks. Given the gas surface density, we derived an analytical total dust surface density by taking into acc…
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…
Herschel PACS observations of 4-10 Myr old Classical T Tauri stars in Orion OB1
Karina Maucó, César Briceño, Nuria Calvet +12
We present \emph{Herschel} PACS observations of 8 Classical T Tauri Stars in the Myr old OB1a and the Myr old OB1b Orion sub-asscociations. Detailed modeling…
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…
