Infrared spectroscopy of the recent outburst in V1047 Cen (Nova Centauri 2005).
T. R. Geballe,Dipankar P. K. Banerjee,A. Evans,Robert D. Gehrz,Charles E. Woodward,Przemek Mróz,Andrzej Udalski,Ulisse Munari,Sumner Starrfield,K. L. Page,Kirill Sokolovsky,Franz-Josef Hambsch,Gordon Myers,Elias Aydi,David A. H. Buckley,F. M. Walter,R. M. Wagner +16 more
TL;DR: In this article, the authors present near-infrared spectroscopy to show that the present outburst is most likely a dwarf nova (DN) eruption, and discuss the possible reasons for its early occurrence.

ZTFJ0038+2030: a long period eclipsing white dwarf and a substellar companion
Jan van Roestel,Thomas Kupfer,Keaton J. Bell,Kevin B. Burdge,Przemek Mróz,Thomas A. Prince,Eric C. Bellm,Andrew J. Drake,Richard Dekany,Ashish Mahabal,Michael Porter,Reed Riddle,Kyung Min Shin,David L. Shupe +13 more
TL;DR: In this paper, the authors identified a deep eclipsing white dwarf with a dark, substellar companion, and obtained high-speed photometry and radial velocity measurements to characterize the system.
Journal ArticleDOI
Identifying Microlensing Events Using Neural Networks
TL;DR: In this paper, the authors presented two simple neural-network-based classifiers for detecting single and binary microlensing events from OGLE-III and OGLEIV data sets.

TL;DR: In this paper, the authors presented the analysis of OGLE-2018-BLG-0022 that is detected toward the Galactic bulge field and demonstrated that the dense and continuous coverage with the high-quality photometry data from ground-based observations combined with the space-based Spitzer observations of this long time-scale event enables them to uniquely determine the masses of the individual lens components.

OGLE-GAL-ACEP-091 -- The First Known Multi-Mode Anomalous Cepheid
Igor Soszyński,Radosław Smolec,Andrzej Udalski,Michał K. Szymański,Paweł Pietrukowicz,D. M. Skowron,Jan Skowron,Przemek Mróz,Radosław Poleski,S. Kozłowski,Patryk Iwanek,Marcin Wrona,Mariusz Gromadzki,Krzysztof Ulaczyk,Krzysztof A. Rybicki +14 more
TL;DR: The first candidate for an anomalous Cepheid pulsating in more than one radial mode - OGLE-GAL-ACEP-091 - was recently identified in the Milky Way based on the photometric database of the Optical Gravitational Lensing Experiment (OGLE) survey as discussed by the authors.
