Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581
João Gomes da Silva, Elisa Delgado-Mena, Nuno C. Santos +145
Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the RV method. The aim of this work is to measure the effect of activity in t…
Dense clumps survive in the vicinity of R136 in 30 Doradus
M. T. Valdivia-Mena, M. Rubio, V. M. Kalari +5
Context: The young massive cluster R136 at the center of 30 Doradus (30 Dor) in the Large Magellanic Cloud (LMC) generates a cavity in the surrounding molecular cloud. However, the…
Euclid: Galaxy morphology and photometry from bulge-disc decomposition of Early Release Observations
L. Quilley, V. de Lapparent, M. Bolzonella +168
The background galaxies in Euclid ERO images of the Perseus cluster make up a remarkable sample in its combination of 0.57 deg area, 25.3 and 23.2 AB mag depth, as well as 0.1"…
The HD 98800 quadruple pre-main sequence system. Towards full orbital characterisation using long-baseline infrared interferometry
S. Zúñiga-Fernández, J. Olofsson, A. Bayo +8
HD 98800 is a young ( Myr old) and nearby ( pc) quadruple system, composed of two spectroscopic binaries orbiting around each other (AaAb and BaBb), with a gas-rich…
Sr and Ba abundance determinations: comparing machine-learning with star-by-star analyses -- High-resolution re-analysis of suspected LAMOST barium stars
D. Karinkuzhi, S. Van Eck, A. Jorissen +6
A new large sample of 895 s-process-rich candidates out of 454180 giant stars surveyed by LAMOST at low spectral resolution (R ~ 1800) has been reported by Norfolk et al. (2019; he…
A Mexican Hat with holes: calculating low resolution power spectra from data with gaps
P. Arevalo, E. Churazov, I. Zhuravleva +2
A simple method for calculating a low-resolution power spectrum from data with gaps is described. The method is a modification of the -variance method previously described by St…
