The Age Distribution of Stellar Orbit Space Clumps
Verena Fürnkranz, Hans-Walter Rix, Johanna Coronado +1
The orbit distribution of young stars in the Galactic disk is highly structured, from well-defined clusters to streams of stars that may be widely dispersed across the sky, but are…
Pearls on a String: Numerous Stellar Clusters Strung along the Same Orbit
Johanna Coronado, Verena Fürnkranz, Hans-Walter Rix
Stars originate from the dense interstellar medium, which exhibits filamentary structure to scales of kpc in galaxies like our Milky Way. We explore quantitatively how muc…
Chemically peculiar A and F stars with enhanced s-process and iron-peak elements: stellar radiative acceleration at work
Maosheng Xiang, Hans-Walter Rix, Yuan-Sen Ting +6
We present metal-rich (dex) A and F stars whose surface abundances deviate strongly from Solar abundance ratios and cannot plausibly reflect the…
From birth associations to field stars: mapping the small-scale orbit distribution in the Galactic disc
Johanna Coronado, Hans-Walter Rix, Wilma H. Trick +3
Stars born at the same time in the same place should have formed from gas of the same element composition. But most stars subsequently disperse from their birth siblings, in orbit…
The R-Process Alliance: Spectroscopic Follow-up of Low-Metallicity Star Candidates from the Best & Brightest Survey
Vinicius M. Placco, Rafael M. Santucci, Timothy C. Beers +17
We present results from an observing campaign to identify low-metallicity stars in the Best & Brightest Survey. From medium-resolution (R ~ 1, 200 - 2, 000) spectroscopy of 857 can…
Discriminating among theories of spiral structure using Gaia DR2
J. A. Sellwood, Wilma Trick, Ray Carlberg +2
We compare the distribution in position and velocity of nearby stars from the Gaia DR2 radial velocity sample with predictions of current theories for spirals in disc galaxies. Alt…
Spectroscopic Validation of Low-Metallicity Stars from RAVE
Vinicius M. Placco, Timothy C. Beers, Rafael M. Santucci +16
We present results from a medium-resolution (R ~ 2, 000) spectroscopic follow-up campaign of 1,694 bright (V < 13.5), very metal-poor star candidates from the RAdial Velocity Exper…
The Galactic Disc in Action Space as seen by Gaia DR2
Wilma H. Trick, Johanna Coronado, Hans-Walter Rix
The quality and quantity of 6D stellar position-velocity measurements in the second Gaia data release (DR2) allows to study small-scale structure in the orbit distribution of the G…
Unbiased TGASLAMOST distances and the role of binarity
Johanna Coronado, Hans-Walter Rix, Wilma H. Trick
Spectrophotometric distances to stars observed by large spectroscopic surveys offer a crucial complement to parallax distances that remain very important also after the future Gaia…
A Distant Sample of Halo Wide Binaries from SDSS
Johanna Coronado, María Paz Sepúlveda, Andrew Gould +1
Samples of reliably identified halo wide binaries are scarce. If reasonably free from selection effects and with a small degree of contamination by chance alignments, these wide bi…
Orbital and physical parameters of eclipsing binaries from the All-Sky Automated Survey catalogue - VII. V1200 Centauri: a bright triple in the Hyades moving group
J. Coronado, K. G. Hełminiak, L. Vanzi +6
We present the orbital and physical parameters of the detached eclipsing binary V1200~Centauri (ASAS~J135218-3837.3) from the analysis of spectroscopic observations and light curve…
