Doctoral INPhINIT fellowships incoming: exoplanet studies: radial velocities and atmospheres

Application deadline:

Our group is currently formed by three senior staff researchers (José A. Caballero, Jorge Sanz Forcada, and María Rosa Zapatero Osorio), one postdoctoral fellow (Esther González Álvarez), and a PhD student (Carlos Cifuentes).

Our work covers the following topics: planet discoveries around stars using radial velocity measurements, isolated planets and brown dwarfs in young stellar clusters, planets and brown dwarfs around stars of the solar neighborhood, the impact of stellar activity on planetary atmospheres, rotation and variability of ultracool dwarfs, and linear polarimetric properties of dusty atmospheres of ultracool dwarfs. Our group is very productive in terms of refereed publications in high-impact journals, with over 310 refereed publications since 1995 that have received an outstanding ~10000 citations (self-citations are removed). We have access to Guaranteed Time Observations (GTO) of the CARMENES and ESPRESSO projects. They are two stable, high resolution spectrographs capable of providing radial velocity measurements with precisions of about 1 m/s (CARMENES) and 10 cm/s (ESPRESSO). CARMENES is operating at the 3.5 m telescope of Calar Alto Observatory and ESPRESSO is located at the 8-m VLT on the Paranal Observatory (ESPRESSO can also operate using the 4 units of VLT simultaneously). CARMENES GTO data are already available since 2016, and ESPRESSO GTO started in September 2018. Our group is also involved in the ARIEL (Atmospheric Remote-Sensing Infrared Exoplanet Large-survey) project, the ESA medium class space mission that will be likely launched in 2028. ARIEL will investigate the atmospheres of ~1000 planets orbiting stars, with the main focus on exotic, hot planets in orbits very close to their star. This is the right time to hire a PhD student who will take advantage of plenty high-quality data available to the team, will be guided by experts in the field, and will work in the environment of international collaborations.

One PhD student will be introduced in the field of exoplanets orbiting stars and high-resolution spectroscopy, with particular emphasis on exoplanet atmospheres at optical and infrared wavelengths mainly using CARMENES and ESPRESSO GTO data. Given our group’s involvement in the space mission ARIEL, the future of the PhD student is very promising. The PhD student will interact with an active group and with researchers that have wide expertise in different observational and analysis techniques (astrometry, photometry, spectroscopy) and cover a wide range of wavelengths (from X-rays through the infrared).
