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…
Molecules in the shadows of the protoplanetary disk HD 143006: Evidence for C/O from simultaneously modeling fourteen ALMA lines
S. E. van Terwisga, P. Woitke, A. M. Weiss +2
The inner disk of the T Tauri star HD 143006 is inclined and casts a broad shadow on a large portion of the outer disk. We use this extraordinary geometry to study the impact of st…
XUE. ProDiMo models of internally and externally irradiated planet-forming disks around 0.3-4.0 solar mass stars (The IRIS project I)
Jenny Frediani, Konstantin V. Getman, Peter Woitke +18
Most stars and planets form in massive star-forming regions, where disks are exposed to external far-ultraviolet (FUV) radiation from nearby O- and B-type stars. The combined effec…
The Effect of X-Ray and Accretion Variability on Mid-Infrared Lines in the Young Disk-Bearing Binary DQ Tau
Bayron Portilla-Revelo, Konstantin V. Getman, Ágnes Kóspál +5
A star's radiation field is the main energy source of a planet-forming disk. Stellar photons---from X-rays to optical---are reprocessed in the inner protoplanetary disk enabling mi…
X-shooter survey Across Regions and Ages to probe Disk Evolution (ARADE): Accretion properties in Orion A and their relation with disk masses
Lara Piscarreta, Giacomo Beccari, Carlo Manara +10
We present a homogeneous VLT/X-Shooter study of accretion in young stellar objects spanning the entire Orion A complex. Our sample includes 91 pre-main-sequence stars hosting a pro…
The small transiting planet population revealed by ESPRESSO with extreme precision radial velocities
M. J. Hobson, B. Lavie, F. Bouchy +35
Small planets are extremely common in the Galaxy, including planets with masses and radii between those of Earth and Neptune. Characterizing these planets' masses requires ultra-pr…
How the gradient of versus UV field strength yields insights into the ages of protoplanetary disc populations
Gavin A. L. Coleman, Sierk E. van Terwisga
FUV radiation from massive stars launch photoevaporative winds from the outer regions of protoplanetary discs around other stars, removing gas and dust. Observations have identifie…
Probing accretion and stellar properties in the Orion Nebula with VLT/X-Shooter
L. Piscarreta, G. Beccari, R. A. B. Claes +6
Multiple photometric studies have reported the presence of seemingly older accreting pre-main sequence stars (PMS) in optical colour-magnitude diagrams (CMDs). We investigate this…
Identification of a turnover in the initial mass function of a young stellar cluster down to 0.5 M
Matthew De Furio, Michael R. Meyer, Thomas Greene +11
A successful theory of star formation should predict the number of objects as a function of their mass produced through star-forming events. Previous studies in star-forming region…
PRODIGE -- Planet-forming disks in Taurus with NOEMA
R. Franceschi, Th. Henning, G. V. Smirnov-Pinchukov +17
We aim to constrain the gas density and temperature distributions as well as gas masses in several T Tauri protoplanetary disks located in Taurus. We use the 12CO, 13CO, and C18O (…
PRODIGE -- Planet-forming disks in Taurus with NOEMA. I. Overview and first results for 12CO, 13CO, and C18O
D. Semenov, Th. Henning, S. Guilloteau +21
We are performing a line survey of 8 planet-forming Class II disks in Taurus with the IRAM NOrthern Extended Millimeter Array (NOEMA), as a part of the MPG-IRAM Observatory Program…
X-ray, Near-Ultraviolet, and Optical Flares Produced By Colliding Magnetospheres in The Young High-Eccentricity Binary DQ Tau
Konstantin V. Getman, Ágnes Kóspál, Nicole Arulanantham +3
DQ Tau is a unique young high-eccentricity binary system that exhibits regular magnetic reconnection flares and pulsed accretion near periastron. We conducted NuSTAR, Swift, and Ch…
XUE. Molecular inventory in the inner region of an extremely irradiated Protoplanetary Disk
María Claudia Ramirez-Tannus, Arjan Bik, Lars Cuijpers +24
We present the first results of the eXtreme UV Environments (XUE) James Webb Space Telescope (JWST) program, that focuses on the characterization of planet forming disks in massive…
Survey of Orion Disks with ALMA (SODA) II: UV-driven disk mass loss in L1641 and L1647
S. E. van Terwisga, A. Hacar
External FUV irradiation of protoplanetary disks has an important impact on their evolution and ability to form planets. However, nearby (<300 pc) star-forming regions lack suffici…
The Young Binary DQ Tau Produces Another X-ray Flare Near Periastron
Konstantin V. Getman, Vitaly V. Akimkin, Nicole Arulanantham +4
This work is part of a multi-wavelength program to study the effects of X-ray/UV/optical stellar radiation on the chemistry of the circumbinary disk around the young high-eccentric…

Effects of stellar density on the photoevaporation of circumstellar discs
Francisca Concha-Ramírez, Maite J. C. Wilhelm, Simon Portegies Zwart +2

Disk masses in the Orion Molecular Cloud-2: distinguishing time and environment
Sierk. E. van Terwisga, Alvaro Hacar, Ewine F. van Dishoeck
The mass evolution of protoplanetary disks is driven by both internal processes and external factors, such as photoevaporation. Disentangling these two effects, however, has remain…
