The refractory fraction of phosphorus in planet-forming discs

Sandipan P. D. Borthakur, Mihkel Kama, Luca Fossati +3

Context. Phosphorus (P) is an essential element for life on Earth and a potential tracer of planet formation history. However, there has been no detection of P-bearing molecules in…

The Tartu Observatory Fiber-fed Echelle Spectrograph (TOFES) Data Reduction Pipeline

Sandipan P. D. Borthakur, Tõnis Eenmäe, Nikolai Piskunov +9

We introduce the data reduction pipeline for the Tartu Observatory Fiber-fed Echelle Spectrograph (TOFES). TOFES is installed in the Coudé room and will be connected to the 1.5 m T…

Investigating Circumstellar Atomic Radiation-driven Dynamics

A. Lehtmets, M. Kama, L. Fossati +1

The interactions between stars and their orbiting planets, driven by forces such as stellar radiation and gravity, play an essential role in shaping exoplanetary atmospheres and ga…

Abundance analysis of stars hosting gas-rich debris disks

Sandipan P. D. Borthakur, Mihkel Kama, Luca Fossati +4

Accretion from protoplanetary or debris disks can contaminate the stellar photosphere, which is detectable in stars with radiative envelopes due to relatively slower photospheric m…

A rare phosphorus-rich star in an eclipsing binary from TESS

Colin P. Folsom, Mihkel Kama, Tõnis Eenmäe +6

Context: Few exoplanets around hot stars with radiative envelopes have been discovered, although new observations from the TESS mission are improving this. Stars with radiative env…

Ariel: Enabling planetary science across light-years

Giovanna Tinetti, Paul Eccleston, Carole Haswell +313

Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
