The recent era of large, ground-based abundance surveys has unraveled the chemical structures of our Milky Way galaxy. The most striking abundance feature is the alpha-abundance bimodality. The low-alpha stars are younger (1-8 Gyr) while the high-alpha stars are older (8-12 Gyr) and have a thicker distribution. There are a number of different

We propose to observe the Ring Nebula, NGC 6720, at unprecedented spatial resolution and spectral sensitivity using MIRI, NIRSpec and NIRCam, with the aim of measuring and analyzing the emission from a range of atomic, molecular and particulate components commonly found in astrophysical environments. We will use this planetary nebula (PN) as an

The atmospheric characterisation of multiple exoplanets in the same system can provide a window into the processes that underpinned their formation and evolution. The planetary C/O ratios are of particular interest as they encode information about where the planet formed with respect to different ice lines, but precise measurements of this using

Galaxy evolution models are strongly underpinned by anchoring constraints made locally in the Milky Way. In this proposal, we aim to perform a pilot study toward providing a secondary local anchor in the form of a detailed mapping in element abundances of the stellar populations of the Andromeda galaxy, M31. Primarily, we will use NIRSpec

More than 10% of the barred galaxies with a direct measurement of bar pattern speed host a bar rotating extremely fast. These bars are generally defined as 'ultrafast'. We selected the ultrafast bars observed in CALIFA and investigated if the bar rotation rates were correctly determined. We tested the measurement of bar pattern speed obtained with

The stellar initial mass function (IMF) is a fundamental ingredient in stellar population synthesis models and for decades it was considered to be universal. However, the universality of the IMF has been recently challenged by detailed stellar population modeling of massive early-type galaxies. I this talk I will present our recent efforts within
