FF Aql BV light curves
Photographic plates of the Harvard Observatory stacks have been used to obtain 1261 brightness estimates for the low-amplitude Cepheid FF Aql (P=4.47 days). Combined with... -
Light curves of V838 Mon and V4332 Sgr
We analyze spectra of V838 Mon and V4332 Sgr taken in 2004-2005 using the 6m telescope of the Special Astrophysical Observatory with the UAGS and SCORPIO spectrographs. We... -
UBVJHKLM Photometry of Nova Cygni 1992
The results of photometric UBVJHKLM observations of Nova Cygni 1992 performed from the 83d until the 290th day after the nova outburst are presented. The accuracy of the... -
Light curves of RR Lyrae stars in M3 (NGC5272)
The overtone and multi-mode RR Lyrae stars in the globular cluster M3 are studied using a 200 day long, B,V, and l_c_ time-series photometry obtained in 2012. 70% of the 52... -
Intrinsic colors and temperatures of PMS stars
We present an analysis of the intrinsic colors and temperatures of 5-30 Myr old pre-main-sequence (pre-MS) stars using the F0- through M9-type members of nearby, negligibly... -
riz photometry in Cyg OB2
In order to fully understand the gravitational collapse of molecular clouds, the star formation process, and the evolution of circumstellar disks, these phenomena must be... -
Detailed analysis of cool WDs in the SDSS
We present optical spectroscopy and near-infrared photometry of 126 cool white dwarfs (WDs) in the Sloan Digital Sky Survey (SDSS DR3). Our sample includes high proper motion... -
Photometric histories of recurrent novae
I collect virtually all photometry of the 10 known galactic recurrent novae (RNe) and their 37 known eruptions. This consists of my modern measures of nearly all archival plates... -
UBVRcIc photometry of FHB and metal-poor stars
We report broadband UBV and/or BVR_C_I_C_ CCD photometry for a total of 1857 stars in the thick-disk and halo populations of the Galaxy. The majority of our targets were... -
BVRIJHK photometry of cool white dwarfs
A detailed photometric and spectroscopic analysis of cool (T_eff_<~12000K) white dwarf stars is presented. The sample has been drawn from the Yale Parallax Catalog and from a... -
HST photometry of M4
This paper presents a detailed description of the acquisition and processing of a large body of imaging data for three fields in the globular cluster M4 taken with the Wide... -
Periodic dwarf carbon stars from ZTF & Gaia
Dwarf carbon (dC) stars, main-sequence stars showing carbon molecular bands, are enriched by mass transfer from a previous asymptotic-giant-branch (AGB) companion, which has... -
LBT photometry in Pisces II and Pegasus III
We have used B, V time-series photometry collected with the Large Binocular Telescope to undertake the first study of variable stars in the Milky Way ultra-faint dwarf (UFD)... -
Dwarf nova outbursts detected by ASAS-SN
The unprecedented sky coverage and observing cadence of the All-Sky Automated Survey for SuperNovae (ASAS-SN) has resulted in the discovery and continued monitoring of a large... -
AAVSO and DASCH light curve of U Mon
We present an X-ray through submillimeter observations of the classical RV Tauri (RVb-type) variable U Mon, a post-asymptotic giant branch (AGB) binary with a circumbinary disk... -
SMEI photometry of Betelgeuse
We conduct a rigorous examination of the nearby red supergiant Betelgeuse by drawing on the synthesis of new observational data and three different modeling techniques. Our... -
Spectroscopic binary multiplicity with Robo-AO
We present higher-order multiplicity results for 60 solar-type spectroscopic binaries based on 0.75{mu}m imaging data taken by the robotic adaptive optics (Robo-AO) system at... -
SN 2018hna photometry & spectroscopy obs.
High-cadence ultraviolet, optical, and near-infrared photometric and low-resolution spectroscopic observations of the peculiar Type II supernova (SN) 2018hna are presented. The... -
BVRI photom. of DV Psc and known short-period EBs
Using 27 sets of new multiband photometry light curves acquired from our long-term photometric campaign carried out in the last 5yr and high-resolution spectroscopic data from... -
Opt & NIR SMARTS/ANDICAM photometry for DQ Tau
We present multiepoch optical and near-infrared (NIR) photometry and spectroscopy of the spectroscopic binary T Tauri star DQ Tau. The photometric monitoring, obtained using...
