Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way
L. M. Howes, A. R. Casey, M. Asplund +22
The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars…
OGLE Atlas of Classical Novae. II. Magellanic Clouds
P. Mroz, A. Udalski, R. Poleski +8
The population of classical novae in the Magellanic Clouds was poorly known because of a lack of systematic studies. There were some suggestions that nova rates per unit mass in th…
MOA-2010-BLG-353Lb A Possible Saturn Revealed
N. J. Rattenbury, D. P. Bennett, T. Sumi +30
We report the discovery of a possible planet in microlensing event MOA-2010-BLG-353. This event was only recognised as having a planetary signal after the microlensing event had fi…
Black Hole, Neutron Star and White Dwarf Candidates from Microlensing with OGLE-III
L. Wyrzykowski, Z. Kostrzewa-Rutkowska, J. Skowron +13
Most stellar remnants so far have been found in binary systems, where they interact with matter from their companions. Isolated neutron stars and black holes are difficult to find…
The OGLE Collection of Variable Stars. Anomalous Cepheids in the Magellanic Clouds
I. Soszynski, A. Udalski, M. K. Szymanski +10
We present a collection of 250 anomalous Cepheids (ACs) discovered in the OGLE-IV fields toward the Large (LMC) and Small Magellanic Cloud (SMC). The LMC sample is an extension of…
Planet Sensitivity from Combined Ground- and Space-based Microlensing Observations
Wei Zhu, Andrew Gould, Charles Beichman +45
To move one step forward toward a Galactic distribution of planets, we present the first planet sensitivity analysis for microlensing events with simultaneous observations from spa…
OGLE-2012-BLG-0563Lb: a Saturn-mass Planet around an M Dwarf with the Mass Constrained by Subaru AO imaging
A. Fukui, A. Gould, T. Sumi +58
We report the discovery of a microlensing exoplanet OGLE-2012-BLG-0563Lb with the planet-star mass ratio ~1 x 10^{-3}. Intensive photometric observations of a high-magnification mi…
OGLE Atlas of Classical Novae I. Galactic Bulge Objects
P. Mroz, A. Udalski, R. Poleski +8
Eruptions of classical novae are possible sources of lithium formation and gamma-ray emission. Nova remnants can also become Type Ia supernovae (SNe Ia). The contribution of novae…
