# Projects

#### DIANA Project

DIANA is an European Framework Seven (FP7) project, SPACE-2011 collaboration, project no 284405, which conducts a systematic collection and coherent analysis of observational data from the birth-places of extrasolar planets, the so-called protoplanetary discs. DIANA stands for DIscANAlysis.

#### ITN CHAMELEON

In the CHAMELEON Marie-Curie Innovative Training Network (MC-ITN), we focus on the development of Virtual Laboratories which will be the crucial tool to analyse in detail current and future disk and exoplanet observations. Our goals are to retrieve and predict the chemical composition of planet-forming disks and exoplanet atmospheres using such Virtual Laboratories. We plan to achieve knowledge transfer between planet and disk community by the exchange of state-of-the-art codes developing models and to train our researchers in complex modelling and big-data interpretation. We will use the fascination for exoplanets and their birthplaces to promote science in the society, in local and wider communities.

#### oLife

A joint initiative by seven world-leading research institutes of three universities in The Netherlands. Supported by funding from the Horizon 2020 Framework Programme of the European Union, we offer 18 post-doctoral fellowships for interdisciplinary research on fundamental questions concerning the origin and evolution of life, and its distribution in the universe.

#### The Science Performance of JWST as Characterized in Commissioning

21
Nov, 2022

This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performance of the spacecraft, telescope, science instruments, and ground system, with an emphasis on differences from pre-la...

#### Interpreting molecular hydrogen and atomic oxygen line emission of T Tauri disks with photoevaporative disk-wind models

18
Nov, 2022

Winds in protoplanetary disks play an important role in their evolution and dispersal. However, what physical process is driving the winds is still unclear (i.e. magnetically vs thermally driven), and can only be understood by directly confronting theoretical models with observational data. We ...

#### The kinematics and excitation of infrared water vapor emission from planet-forming disks: results from spectrally-resolved surveys and guidelines for JWST spectra

16
Nov, 2022

This work presents ground-based spectrally-resolved water emission at R = 30000-100000 over infrared wavelengths covered by JWST (2.9-12.8 $\mu$m). Two new surveys with iSHELL and VISIR are combined with previous spectra from CRIRES and TEXES to cover parts of multiple ro-vibrational and rotati...

#### An accurate set of H$_3$O$^+ -$ H$_2$ collisional rate coefficients for non-LTE modelling of warm interstellar clouds

04
Nov, 2022

Hydronium (H$_3$O$^+$) was first detected in 1986 in interstellar molecular clouds. It was reported in many galactic diffuse and dense regions, as well as in extragalactic sources. H$_3$O$^+$ plays a major role both in interstellar oxygen and water chemistry. However, despite the large number o...

#### Mixing and diffusion in protoplanetary disc chemistry

25
Sep, 2022

We develop a simple iterative scheme to include vertical turbulent mixing and diffusion in ProDiMo thermo-chemical models for protoplanetary discs. The models are carefully checked for convergence toward the time-independent solution of the reaction-diffusion equations, as e.g. used in exoplane...

#### Nuclear High-Ionization Outflow in the Compton-Thick AGN NGC 6552 as seen with \textit{JWST} Mid-Infrared Spectroscopy

04
Sep, 2022

During the commissioning of the James Webb Space Telescope (JWST), the Mid-Infrared Instrument (MIRI) observed NGC 6552 with the MIRI Imager and the Medium-Resolution Spectrograph (MRS). NGC 6552 is an active galactic nucleus (AGN) at redshift 0.0266 classified as a Seyfert 2 nucleus in the opt...
