Precise Measures of Orbital Period, Before and After Nova Eruption for QZ Aurigae
Bradley E. Schaefer, David Boyd, Geoffrey C. Clayton +7
For the ordinary classical nova QZ Aurigae (which erupted in 1964), we report 1317 magnitudes from 1912--2016, including four eclipses detected on archival photographic plates from…
Discovery of the 2010 Eruption and the Pre-Eruption Light Curve for Recurrent Nova U Scorpii
Bradley E. Schaefer, Ashley Pagnotta, Limin Xiao +12
We report the discovery by B. G. Harris and S. Dvorak on JD 2455224.9385 (2010 Jan 28.4385 UT) of the predicted eruption of the recurrent nova U Scorpii (U Sco). We also report on…
Long-Term Light Curve of Highly-Variable Protostellar Star GM Cep
Limin Xiao, Peter Kroll, Arne A. Henden
We present data from the archival plates at Harvard College Observatory and Sonneberg Observatory showing the field of the solar type pre-main sequence star GM Cep. A total of 186…
Estimating Redshifts for Long Gamma-Ray Bursts
Limin Xiao, Bradley E. Schaefer
We are constructing a program to estimate the redshifts for GRBs from the original Swift light curves and spectra, aiming to get redshifts for the Swift bursts \textit{without} spe…
The Behavior of Novae Light Curves Before Eruption
Andrew C. Collazzi, Bradley E. Schaefer, Limin Xiao +4
In 1975, E. R. Robinson conducted the hallmark study of the behavior of classical nova light curves before eruption, and this work has now become part of the standard knowledge of…
Discovery of a Second Nova Eruption of V2487 Ophiuchi
Ashley Pagnotta, Bradley E. Schaefer, Limin Xiao +2
A directed search for previously-undiscovered nova eruptions was conducted in the astronomical plate archives at Harvard College Observatory and Sonneberg Observatory. We found tha…
Are Swift Long-Lag Gamma-Ray Bursts in the Local Supercluster?
Limin Xiao, Bradley E. Schaefer
A sample of 18 long-lag (tau_{lag} > 1 s) Gamma-Ray Bursts (GRBs) has been drawn from our catalog of all Swift long GRBs. Four different tests are done on this sample to test the p…
GRB060614 is at High Redshift, So No New Class of Gamma-Ray Bursts is Required
Bradley E. Schaefer, Limin Xiao
Long duration Gamma-Ray Bursts (GRBs) have been strongly connected with core collapse supernovae, so it was surprising when the recent GRB060614 (with a reported redshift of 0.125)…
