Into the Darkness: Classical and Type II Cepheids in the Zona Galactica Incognita
István Dékány, Gergely Hajdu, Eva K. Grebel +1
The far side of the Milky Way's disk is one of the most concealed parts of the known Universe due to extremely high interstellar extinction and point source density toward low Gala…
On the optimal calibration of VVV photometry
Gergely Hajdu, István Dékány, Márcio Catelan +1
Prompted by some inconsistencies in the photometry of the VISTA Variables in the Vía Láctea (VVV) survey, we conduct a revision of the standard calibration procedure of VISTA data…
On the Oosterhoff dichotomy in the Galactic bulge: II. kinematical distribution
Z. Prudil, I. Dékány, E. K. Grebel +3
We present a kinematical study of RR~Lyrae stars associated with two Oosterhoff groups in the Galactic bulge. We used data published in the first paper of the series, plus proper m…
Analysis of the physical nature of 22 New VVV Survey Globular Cluster candidates in the Milky Way Bulge
Tali Palma, Dante Minniti, Javier Alonso-García +11
In order to characterize 22 new globular cluster (GC) candidates in the Galactic bulge, we present their colour-magnitude diagrams (CMDs) and Ks-band luminosity functions (LFs) usi…
New constraints on the nuclear equation of state from the thermal emission of neutron stars in quiescent low-mass X-ray binaries
N. Baillot d'Etivaux, S. Guillot, J. Margueron +3
This paper presents a new analysis of the thermal emission from the neutron star surface to constrain the dense matter equation of state. It is based on the use of a Markov-Chain M…
New type II Cepheids from VVV data towards the Galactic center
V. F. Braga, R. Contreras Ramos, D. Minniti +5
The Galactic center (GC) is the densest region of the Milky Way. Variability surveys towards the GC potentially provide the largest number of variable stars per square degree withi…
The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition
The MSE Science Team, Carine Babusiaux, Maria Bergemann +258
(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unvei…
An Algorithm for the Visualization of Relevant Patterns in Astronomical Light Curves
Christian Pieringer, Karim Pichara, Márcio Catelán +1
Within the last years, the classification of variable stars with Machine Learning has become a mainstream area of research. Recently, visualization of time series is attracting mor…
Stellar Astrophysics and Exoplanet Science with the Maunakea Spectroscopic Explorer (MSE)
Maria Bergemann, Daniel Huber, Vardan Adibekyan +70
The Maunakea Spectroscopic Explorer (MSE) is a planned 11.25-m aperture facility with a 1.5 square degree field of view that will be fully dedicated to multi-object spectroscopy. A…
Variable Stars in Sagittarius Globular Clusters I. Arp~2
Barton J. Pritzl, Thomas C. Gehrman, Ricardo Salinas +3
We present new photometry and analysis of the twelve variable stars (nine RR Lyrae, three SX Phoenicis) belonging to the Sagittarius globular cluster Arp 2. Of the nine RR Lyrae st…
On the Oosterhoff dichotomy in the Galactic bulge: I. spatial distribution
Z. Prudil, I. Dékány, M. Catelan +3
We present a study of the Oosterhoff (Oo) dichotomy in the Galactic bulge using 8\,141 fundamental mode RR~Lyrae stars. We used public photometric data from the Optical Gravitation…
