# 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.

#### SAFARI/SPICA Project

SPICA is a joint European-Japanese project under phase-A study at ESA: an infrared space observatory with a large, cryogenically cooled telescope. One of the instruments on board is SAFARI, a far-IR spectrometer providing instantaneously wavelength coverage of the 34 to 230 micron domain. One of the core objectives of this mission is to trace the gas, dust and ice evolution in planetary systems.

#### 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.

#### Six transiting planets and a chain of Laplace resonances in TOI-178

22
Jan, 2021

Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are especially important as the fragility of their orbital configuration ensures that no significant scattering or collisional event has taken pla...

#### Late-time Observations of Calcium-Rich Transient SN 2019ehk Reveal a Pure Radioactive Decay Power Source

22
Jan, 2021

We present $\textit{Hubble Space Telescope}$ imaging of the Calcium-rich supernova (SN) 2019ehk at 276 - 389 days after explosion. These observations represent the latest photometric measurements of a Calcium-rich transient to date and allows for the first opportunity to analyze the late-time e...

#### Benchmarking Dust Emission Models in M101

22
Jan, 2021

We present a comparative study of four physical dust models and two single-temperature modified blackbody models by fitting them to the resolved WISE, Spitzer, and Herschel photometry of M101 (NGC 5457). Using identical data and a grid-based fitting technique, we compare the resulting dust and ...
