Testing the Potential for Radio Variability in Disks around T Tauri Stars with Observations and Chemical Modeling
C. C. Espaillat, E. Macias, J. Wendeborn +5
A multiwavelength observing campaign of the T Tauri star (TTS) GM Aur was undertaken in 2019 December that obtained Swift X-ray and NUV fluxes, HST NUV spectra, LCOGT ugri and TESS…
The Evolution Of The Inner Regions of Protoplanetary Disks
Ezequiel Manzo-Martínez, Nuria Calvet, Jesús Hernández +6
We present a study of the evolution of the inner few astronomical units of protoplanetary disks around low-mass stars. We consider nearby stellar groups with ages spanning from 1 t…
A transitional disk around an intermediate mass star in the sparse population of the Orion OB1 Association
Alice Pérez-Blanco, Karina Maucó, Jesús Hernández +8
We present a detailed study of the disk around the intermediate mass star SO 411, aiming to explain the spectral energy distribution of this star. We show that this is a transition…
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…
Chemical Imaging of the CO Snow Line in the HD 163296 Disk
Chunhua Qi, Karin I. Oberg, Sean M. Andrews +5
The condensation fronts (snow lines) of H2O, CO and other abundant volatiles in the midplane of a protoplanetary disk affect several aspects of planet formation. Locating the CO sn…
Imaging the Inner and Outer Gaps of the Pre-Transitional Disk of HD 169142 at 7 mm
Mayra Osorio, Guillem Anglada, Carlos Carrasco-Gonzalez +11
We present Very Large Array observations at 7 mm that trace the thermal emission of large dust grains in the HD 169142 protoplanetary disk. Our images show a ring of enhanced emiss…
