A homogeneous analysis of globular clusters from the APOGEE survey with the BACCHUS code. I. The Northern clusters
T. Masseron, D. A. García-Hernández, Sz. Mészáros +12
We analyze a large sample of 885 GCs giants from the APOGEE survey. We used the Cannon results to separate the red giant branch and the asymptotic giant branch stars, not only allo…
MARVEL Analysis of the Measured High-Resolution Rovibronic Spectra of 90Zr16O
Laura K McKemmish, Jasmin Borsovszky, Katie L Goodhew +8
Zirconium oxide(ZrO) is an important astrophysical molecule that defines the S-star classification class for cool giant stars. Accurate, empirical rovibronic energy levels, with as…
Gaia Data Release 2: All-sky classification of high-amplitude pulsating stars
L. Rimoldini, B. Holl, M. Audard +23
More than half a million of the 1.69 billion sources in Gaia Data Release 2 (DR2) are published with photometric time series that exhibit light variations during the 22 months of o…
Propagating Spectropolarimetric Disturbances in a Large Sunspot
M. Stangalini, S. Jafarzadeh, I. Ermolli +7
We present results derived from the analysis of spectropolarimetric measurements of active region AR12546, which represents one of the largest sunspots to have emerged onto the sol…
Wandering near the red edge: photometric observations of three cool ZZ Ceti stars
Zs. Bognár, M. Paparó, Á. Sódor +11
We summarize our findings on three cool ZZ Ceti type pulsating white dwarfs. We determined eight independent modes in HS 0733+4119, of which seven are new findings. For GD 154, we…
Dispersive shock waves in partially ionised plasmas
I. Ballai, E. Forgacs-Dajka, A. Marcu
Compressional waves propagating in the partially ionised solar lower atmospheric plasmas can easily steepen into nonlinear waves, including shocks. Here we investigate the effect o…
Chaotic dynamics in the pulsation of DF Cygni, as observed by Kepler
E. Plachy, A. Bódi, Z. Kolláth
Pulsations of RV Tauri-type variable stars can be governed by chaotic dynamics. However, observational evidence for this happening is usually hard to come by. Here we use the conti…
The NANOGrav 11-year Data Set: Solar Wind Sounding Through Pulsar Timing
D. R. Madison, J. M. Cordes, Z. Arzoumanian +28
The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has observed dozens of millisecond pulsars for over a decade. We have accrued a large collection of disp…
Varying Driver Velocity Fields in Photospheric MHD Wave Simulations
A. J. Leonard, S. J. Mumford, V. Fedun +1
Torsional motions are ubiquitous in the solar atmosphere. In this work, we perform 3D numerical simulations which mimic a vortex-type photospheric driver with a Gaussian spatial pr…
APOGEE Data Releases 13 and 14: Stellar Parameter and Abundance Comparisons With Independent Analyses
Henrik Jönsson, Carlos Allende Prieto, Jon A. Holtzman +18
Data from the SDSS-IV / Apache Point Observatory Galactic Evolution Experiment (APOGEE-2) have been released as part of SDSS Data Releases 13 (DR13) and 14 (DR14). These include hi…
Observing Kelvin-Helmholtz instability in solar blowout jet
Xiaohong Li, Jun Zhang, Shuhong Yang +2
Kelvin-Helmholtz instability (KHI) is a basic physical process in fluids and magnetized plasmas, with applications successfully modelling e.g. exponentially growing instabilities o…
Searching for new white dwarf pulsators for TESS observations at Konkoly Observatory
Zs. Bognár, Cs. Kalup, Á. Sódor +2
We present the results of our survey searching for new white dwarf pulsators for observations by the TESS space telescope. We collected photometric time-series data on 14 white dwa…
Global Oscillation Pattern in Succeeding Solar Flares
N. Gyenge, R. Erdélyi
The temporal recurrence of micro-flare events is studied in a time interval before and after of major solar flares. Our sample is based on the x-ray flare observations by the Geost…
Automated Swirl Detection Algorithm (ASDA) and Its Application to Simulation and Observational Data
Jiajia Liu, Chris J. Nelson, Robert Erdélyi
Swirling motions in the solar atmosphere have been widely observed in recent years and suggested to play a key role in channeling energy from the photosphere into the corona. Here,…
Gaia Data Release 2: Validation of the classification of RR Lyrae and Cepheid variables with the Kepler and K2 missions
László Molnár, Emese Plachy, Áron L. Juhász +1
The second data release of the Gaia mission includes an advance catalog of variable stars. The classification of these stars are based on sparse photometry from the first 22 months…
Applying the weighted horizontal magnetic gradient method to a simulated flaring Active Region
M. B. Korsos, Piyali Chatterjee, R. Erdelyi
Here, we test the weighted horizontal magnetic gradient () as a flare precursor, introduced by Korsos et. al. (2015, ApJ, 802, L21), by applying it to a magneto-hydrodynamic…
The Second APOKASC Catalog: The Empirical Approach
Marc H. Pinsonneault, Yvonne P. Elsworth, Jamie Tayar +33
