We present a new compilation of Type Ia supernovae (SNe Ia), a new data set of low-redshift
nearby-Hubble-flow SNe, and new analysis procedures to work with these heterogeneous …

We present UBVRIz light curves of the Type Ia SN 1999ee and the Type Ib/c SN 1999ex,
both located in the galaxy IC 5179. SN 1999ee has an extremely well-sampled light curve …

Stellar flares with 10 2–10 7 times more energy than the largest solar flare have recently
been detected from nine normal F and G main-sequence stars by Schaefer, King, and …

We present a color-magnitude diagram (CMD) of NGC 6752 based on post-refurbishment
Planetary Camera 2 observations of its core. The main sequence is broadened and …

We present optical and/or infrared photometry of the Type Ia supernovae SN 1991T, SN
1991bg, SN 1999ek, SN 2001bt, SN 2001cn, SN 2001cz, and SN 2002bo. All but one of these …

Field W Ursae Majoris binaries observe a well-known period-color relation such that systems
containing more massive stars are bluer and have longer orbital periods than systems with …

We consider the effect of binary stars on the main-sequence luminosity functions observed
in the core of globular clusters, with specific reference to NGC 6752. We find that mass …

… When I first read Rubenstein's book I felt very much the same … It is perhaps a fitting coincidence
that Rubenstein discusses Elkins … Auschwitz—that remains Rubenstein's primary concern. …

We report the identification of a W UMa contact binary≲ 2'from the center of the metal-poor
core-collapse globular cluster NGC 6397. The photometric properties of this binary system …

We present spectroscopic and photometric observations of SN 1992ar, the most distant
supernova (SN) in the Cal�n/Tololo Survey. We compare its spectrum with those of nearby Type …
