A Cadence to Reduce Aliasing in LSST
Keaton J. Bell, Kelly M. Hambleton, Michael B. Lund +1
Regular sampling in the time domain results in aliasing in the frequency domain that complicates the accurate determination of the periods of astrophysical variables. We propose to…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
The s process in AGB stars as constrained by a large sample of Barium stars
B. Cseh, M. Lugaro, V. D'Orazi +8
Context. Barium (Ba) stars are dwarf and giant stars enriched in elements heavier than iron produced by the slow neutron-capture process (s process). They belong to binary systems…
Spots, flares, accretion, and obscuration in the pre-main sequence binary DQ Tau
Á. Kóspál, P. Ábrahám, G. Zsidi +4
DQ Tau is a young low-mass spectroscopic binary, consisting of two almost equal-mass stars on a 15.8 d period surrounded by a circumbinary disk. Here, we analyze DQ Tau's light cur…
Shockwave Behaviour in RR Lyrae Stars
Attila Bódi, László Molnár, Emese Plachy +1
Here we present the detailed analysis of some modulated Kepler and K2 RR Lyrae stars that show peculiar bump progression in respect to the pulsation phase.
