The impact of interpolation in high-resolution spectroscopy -- The overlooked role of interpolation in radial velocity extraction
A. M. Silva, D. Doshi, K. Al Moulla +11
We explore the impact of spectral interpolation in radial velocity (RV) time-series extracted through template-based methods. We build synthetic datasets with Gaussian profiles to…
A systematic bias in template-based RV extraction algorithms
André M. Silva, N. C. Santos, J. P. Faria +30
In this paper we identify and explore a previously unidentified, multi meter-per-second, systematic correlation between time and RVs inferred through TM and LBL methods. We evaluat…
Magnetic braking and dynamo evolution of Hydri
A. R. G. Santos, T. S. Metcalfe, O. Kochukhov +3
The evolution of magnetic braking and dynamo processes in subgiant stars is essential for understanding how these stars lose angular momentum. We investigate the magnetic braking a…
Dissecting stellar populations with manifold learning I. Validation of the method on a synthetic Milky Way-like galaxy
A. W. Neitzel, T. L. Campante, D. Bossini +1
Different stellar populations may be identified through differences in chemical, kinematic, and chronological properties, suggesting the interplay of various physical mechanisms th…
Linking the primordial composition of planet building disks to the present-day composition of rocky exoplanets
V. Adibekyan, M. Deal, C. Dorn +16
The composition of rocky planets is strongly driven by the primordial materials in the protoplanetary disk, which can be inferred from the abundances of the host star. Understandin…
Liquid crystal torons in Poiseuille-like flows
Guilherme N. C. Amaral, Hanqing Zhao, Mahmoud Sedahmed +5
Three-dimensional (3D) simulations of the structure of liquid crystal (LC) torons, topologically protected distortions of the LC director field, under material flows are rare but e…
FRA -- A new Fast, Robust and Automated pipeline for the detection and measurement of solar-like oscillations in time-series photometry of red-giant stars
C. Gehan, T. L. Campante, M. S. Cunha +1
We developed, tested and validated a new Fast, Robust and Automated (FRA) tool to detect solar-like oscillations. FRA is based on the detection and measurement of the frequency of…
Planets around evolved intermediate-mass stars in open clusters II. Are there really planets around IC4651No9122, NGC2423No3 and NGC4349No127?
E. Delgado Mena, C. Lovis, N. C. Santos +10
(shorter version)The aim of this work is to search for planets around intermediate-mass stars in open clusters by using RV data obtained with HARPS from an extensive survey with mo…
