Constraining the spatial and thermal structure of the gaseous component of circumstellar disks is crucial for understanding star and planet formation. Models predict that the (Neii) line at 12.81 μm detected in young stellar objects (YSOs) with Spitzer traces disk gas and its response to high-energy radiation, but such (Neii) emission may also originate in shocks within powerful outflows. To distinguish between these potential origins for mid-infrared (Neii) emission and to constrain disk…

On the origin of [Ne II] emission in young stars: mid-infrared and optical observations with the Very Large Telescope
Context. The [Ne II] line 12.81 μm was proposed to be a good tracer of gas in the environments of proto-planetary disks; its origin is explained by different mechanisms: jets in outflows,
Observational constraints on the stellar radiation field impinging on transitional disk atmospheres
Mid-infrared atomic and ionic line ratios measured in spectra of pre-main-sequence stars are sensitive indicators of the hardness of the radiation field impinging on the disk surface. We present a
A HUBBLE SPACE TELESCOPE SURVEY OF H2 EMISSION IN THE CIRCUMSTELLAR ENVIRONMENTS OF YOUNG STARS
The formation timescale and final architecture of exoplanetary systems are closely related to the properties of the molecular disks from which they form. Observations of the spatial distribution and
Probing Stellar Accretion with Mid-infrared Hydrogen Lines
In this paper we investigate the origin of the mid-infrared (IR) hydrogen recombination lines for a sample of 114 disks in different evolutionary stages (full, transitional, and debris disks)
Modelling mid-infrared molecular emission lines from T Tauri stars
We introduce a new modelling framework including the Fast Line Tracer (FLITS) to simulate infrared line emission spectra from protoplanetary discs. This paper focusses on the mid-IR spectral region
TRACING HIGH-ENERGY RADIATION FROM T TAURI STARS USING MID-INFRARED NEON EMISSION FROM DISKS
High-energy radiation from T Tauri stars (TTS) influences the amount and longevity of gas in disks, thereby playing a crucial role in the creation of gas giant planets. Here we probe the high-energy
THE ATOMIC AND MOLECULAR CONTENT OF DISKS AROUND VERY LOW-MASS STARS AND BROWN DWARFS
There is growing observational evidence that disk evolution is stellar-mass-dependent. Here, we show that these dependencies extend to the atomic and molecular content of disk atmospheres. We analyze
The Structure of the Evolved Circumbinary Disk around V4046 Sgr
We present sensitive, sub-arcsecond resolution Submillimeter Array observations of the protoplanetary disk around the nearby, pre-main sequence spectroscopic binary V4046 Sgr. We report for the first
UNDERSTANDING THE ORIGIN OF THE [O I] LOW-VELOCITY COMPONENT FROM T TAURI STARS
The formation time, masses, and location of planets are strongly impacted by the physical mechanisms that disperse protoplanetary disks and the timescale over which protoplanetary material is cleared
Low extreme-ultraviolet luminosities impinging on protoplanetary disks
The amount of high-energy stellar radiation reaching the surface of protoplanetary disks is essential to determine their chemistry and physical evolution. Here, we use millimetric and centimetric
