New Near-Infrared light-curve templates for RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +34
We provide homogeneous optical (UBVRI) and near-infrared (JHK) time series photometry for 254 cluster (omega Cen, M4) and field RR Lyrae (RRL) variables. We ended up with more than…
Burst occurrence in young massive stellar objects
Meyer D. M. -A., Vorobyov E. I., Elbakyan V. G. +3
Episodic accretion-driven outbursts are an extreme manifestation of accretion variability. It has been proposed that the development of gravitational instabilities in the proto-cir…
Solar flares and Kelvin-Helmholtz instabilities: A parameter survey
Wenzhi Ruan, Chun Xia, Rony Keppens
Hard X-ray (HXR) sources are frequently observed near the top of solar flare loops, and the emission is widely ascribed to bremsstrahlung. We here revisit an alternative scenario w…
Explosions of blue supergiants from binary mergers for SN 1987A
Athira Menon, Victor Utrobin, Alexander Heger
Based on the work of Menon & Heger (2017), we present the bolometric light curvesand spectra of the explosions of blue supergiant progenitors from binary mergers. We study SN 1987A…
An investigation of the photometric variability of confirmed and candidate Galactic Be stars using ASAS-3 data
Klaus Bernhard, Sebastián Otero, Stefan Hümmerich +3
We present an investigation of a large sample of confirmed (N=233) and candidate (N=54) Galactic classical Be stars (mean V magnitude range of 6.4 to 12.6 mag), with the main aim o…
New Cepheid variables in the young open clusters Berkeley 51 and Berkeley 55
M. E. Lohr, I. Negueruela, H. M. Tabernero +3
As part of a wider investigation of evolved massive stars in Galactic open clusters, we have spectroscopically identified three candidate classical Cepheids in the little-studied c…
The Arches cluster revisited: II. A massive eclipsing spectroscopic binary in the Arches cluster
M. E. Lohr, J. S. Clark, F. Najarro +3
We have carried out a spectroscopic variability survey of some of the most massive stars in the Arches cluster, using K-band observations obtained with SINFONI on the VLT. One targ…
Accelerating infall and rotational spin-up in the hot molecular core G31.41+0.31
M. T. Beltrán, R. Cesaroni, V. M. Rivilla +20
As part of our effort to search for circumstellar disks around high-mass stellar objects, we observed the well-known core G31.41+0.31 with ALMA at 1.4 mm with an angular resolution…
On the RR Lyrae stars in globulars: V. the complete Near-Infrared (JHKs) census of omega Centauri RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +35
We present a new complete Near-Infrared (NIR, ) census of RR Lyrae stars (RRLs) in the globular Cen (NGC 5139). We collected 15,472 images with 4-8m class telesc…
Accurate effective temperatures of the metal-poor benchmark stars HD 140283, HD 122563 and HD 103095 from CHARA interferometry
I. Karovicova, T. R. White, T. Nordlander +14
Large stellar surveys of the Milky Way require validation with reference to a set of "benchmark" stars whose fundamental properties are well-determined. For metal-poor benchmark st…
