A decade of radial-velocity monitoring of rho Leo: moment analysis and periodic variability
V. A. Checha, A. Aret, I. Kolka +6
We investigate the origin of long-term spectroscopic and photometric variability in the blue supergiant rho Leo, with particular emphasis on distinguishing between intrinsic pulsat…
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…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
Ariel stellar characterisation IV. Fundamental parameters of 18 hot stars in the Ariel mission candidate sample
H. Ramler, S. P. D. Borthakur, C. P. Folsom +16
The characterisation of exoplanetary systems depends on the accurate determination of host star parameters. The Ariel mission will probe the atmospheres of a statistically signific…
Photometric and spectroscopic variability of the blue supergiant rho Leo
V. A. Checha, A. Aret, I. Kolka +12
Context. The post-main-sequence evolution of massive stars remains poorly understood, particularly for blue supergiants. These objects play a crucial role in the dynamical and chem…
Portrait of a Galaxy on FIRE: Is the -bimodality a natural consequence of inside-out disc growth in a hierarchical formation scenario?
María Benito, Annaliina Aavik, Giuseppina Battaglia +7
The chemical dichotomy in the [/Fe]-[Fe/H] plane is a consequence of the complex processes underlying the formation and evolution of disc galaxies such as observed in the stella…
Refractory phosphorus in the HD 100546 protoplanetary disk
Mihkel Kama, Oliver Shorttle, Sandipan P. D. Borthakur +5
The phosphorus budget of planets is intertwined with their formation history and is thought to influence their habitability. The chemical reservoirs and volatile \emph{vs} refracto…
A Bayesian estimation of the Milky Way's circular velocity curve using Gaia DR3
Sven Põder, María Benito, Joosep Pata +5
Our goal is to calculate the circular velocity curve of the Milky Way, along with corresponding uncertainties that quantify various sources of systematic uncertainty in a self-cons…
