An improved standardization framework for Type II-P supernovae using a hierarchical Bayesian approach

A. Holas, S. Taubenberger, C. Vogl +41

We use Type II-P supernovae (SNe II-P) observed as part of the Nearby Supernova Factory (SNfactory) experiment as standardizable candles to develop an improved standardization fram…

Type Ib supernovae are bluer than Type Ic supernovae

Harim Jin, Selma E. de Mink, Sebastian Holzner +5

Type Ib and Ic supernovae (SNe Ib/Ic) are the bright finale of massive stars that have lost their hydrogen envelopes, making them powerful probes of mass stripping in massive star…

Interferometric Images of the Starspot Evolution of Andromedae

Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +21

The evolution of starspots of the giant primaries of RS CVn systems is typically detected indirectly with photometric and spectroscopic monitoring. These observations suggest slowl…

Orbit determination for the binary Cepheid V1344 Aql

B. Cseh, G. Csörnyei, L. Szabados +4

Context. Binary Cepheids play an important role in investigating the calibration of the classical Cepheid period-luminosity relationship. Therefore a thorough study of individual C…

Reeling in the Whirlpool: the distance to M 51 clarified by Cepheids and the Type IIP SN 2005cs

G. Csörnyei, R. I. Anderson, C. Vogl +4

Despite being one of the best-known galaxies, the distance to the Whirlpool Galaxy, M 51, is still debated. Current estimates range from 6.02 to 9.09 Mpc, and different methods yie…

Mid-infrared time-domain study of recent dust production events in the extreme debris disc of TYC 4209-1322-1

A. Moór, P. Ábrahám, Á. Kóspál +23

Extreme debris discs are characterized by unusually strong mid-infrared excess emission, which often proves to be variable. The warm dust in these discs is of transient nature and…

A multi-epoch, multi-wavelength study of the classical FUor V1515 Cyg approaching quiescence

Zs. M. Szabó, Á. Kóspál, P. Ábrahám +28

Historically, FU Orionis-type stars are low-mass, pre-main sequence stars. The members of this class experience powerful accretion outbursts and remain in an enhanced accretion sta…

SN 2018agk: A Prototypical Type Ia Supernova with a Smooth Power-law Rise in Kepler (K2)

Qinan Wang, Armin Rest, Yossef Zenati +73

We present the 30-min cadence Kepler/K2 light curve of the Type Ia supernova (SN Ia) SN 2018agk, covering approximately one week before explosion, the full rise phase and the decli…

A study of the photometric and spectroscopic variations of the prototypical FU Orionis-type star V1057 Cyg

Zs. M. Szabó, Á. Kóspál, P. Ábrahám +19

Among the low-mass pre-main sequence stars, a small group called FU Orionis-type objects (FUors) are notable for undergoing powerful accretion outbursts. V1057 Cyg, a classical exa…

SN 2018zd: An Unusual Stellar Explosion as Part of the Diverse Type II Supernova Landscape

Jujia Zhang, Xiaofeng Wang, Jozsef Vinko +29

We present extensive observations of SN 2018zd covering the first \,d after the explosion. This SN shows a possible shock-breakout signal \,hr after the explosion…

Constraints on the physical properties of Type Ia supernovae from photometry

R. Konyves-Toth, J. Vinko, A. Ordasi +17

We present a photometric study of 17 Type Ia supernovae (SNe) based on multi-color (Bessell BVRI) data taken at Piszkesteto mountain station of Konkoly Observatory, Hungary between…

The Type II-P Supernova 2017eaw: from explosion to the nebular phase

Tamás Szalai, József Vinkó, Réka Könyves-Tóth +36

The nearby SN 2017eaw is a Type II-P (``plateau') supernova showing early-time, moderate CSM interaction. We present a comprehensive study of this SN including the analysis of high…

K2 Observations of SN 2018oh Reveal a Two-Component Rising Light Curve for a Type Ia Supernova

G. Dimitriadis, R. J. Foley, A. Rest +145

We present an exquisite, 30-min cadence Kepler (K2) light curve of the Type Ia supernova (SN Ia) 2018oh (ASASSN-18bt), starting weeks before explosion, covering the moment of explo…
