Revisiting the extremely long-period cataclysmic variables V479 Andromedae and V1082 Sagitarii
Gagik Tovmassian, Diogo Belloni, Anna F. Pala +56
The overwhelming majority of CVs have orbital periods shorter than 10 hr. However, a few have much longer periods, and their formation and existence pose challenges for the CV evol…
A wiggling filamentary jet at the origin of the blazar multi-wavelength behaviour
C. M. Raiteri, M. Villata, M. I. Carnerero +96
Blazars are beamed active galactic nuclei known for their strong multi-wavelength variability on timescales from years down to minutes. We aim to investigate the suitability of the…
MASTER OT J055845.55+391533.4: SU UMa star with a dip and long rebrightening
Taichi Kato, Hiroshi Itoh, Tonny Vanmunster +7
We analyzed Asteroid Terrestrial-impact Last Alert System (ATLAS), Zwicky Transient Facility (ZTF) and All-Sky Automated Survey for Supernovae (ASAS-SN) data of MASTER OT J055845.5…
The multi-wavelength view of shocks in the fastest nova V1674 Her
K. V. Sokolovsky, T. J. Johnson, S. Buson +41
Classical novae are shock-powered multi-wavelength transients triggered by a thermonuclear runaway on an accreting white dwarf. V1674 Her is the fastest nova ever recorded (time to…
The optical behaviour of BL Lacertae at its maximum brightness levels: a blend of geometry and energetics
C. M. Raiteri, M. Villata, S. G. Jorstad +13
In 2021 BL Lacertae underwent an extraordinary activity phase, which was intensively followed by the Whole Earth Blazar Telescope (WEBT) Collaboration. We present the WEBT optical…
The Impact of Contaminated RR Lyrae/Globular Cluster Photometry on the Distance Scale
Daniel J. Majaess, David G. Turner, Wolfgang P. Gieren +1
RR Lyrae variables and the stellar constituents of globular clusters are employed to establish the cosmic distance scale and age of the universe. However, photometry for RR Lyrae v…
Discovery of the Host Cluster for the Fundamental Cepheid Calibrator Zeta Gem
Daniel J. Majaess, David G. Turner, Wolfgang Gieren +2
New and existing CORAVEL, UBVJHKs, HST, HIP/Tycho, ARO, KPNO, and DAO observations imply that the fundamental Cepheid calibrator Zeta Gem is a cluster member. The following paramet…
RR Lyrae and Type II Cepheid Variables Adhere to a Common Distance Relation
Daniel J. Majaess
Preliminary evidence is presented reaffirming that SX Phe, RR Lyrae, and Type II Cepheid variables may be characterized by a common Wesenheit period-magnitude relation, to first or…
Enhancing Our Knowledge of Northern Cepheids through Photometric Monitoring
David G. Turner, Daniel J. Majaess, David J. Lane +4
A selection of known and newly-discovered northern hemisphere Cepheids and related objects are being monitored regularly through CCD observations at the automated Abbey Ridge Obser…
Characteristics of the Galaxy according to Cepheids
Daniel J. Majaess, David G. Turner, David J. Lane
Classical and Type II Cepheids are used to reinvestigate specific properties of the Galaxy. A new Type II reddening-free Cepheid distance parameterization is formulated from LMC Ce…
Assessing potential cluster Cepheids from a new distance and reddening parameterization and 2MASS photometry
Daniel J. Majaess, David G. Turner, David J. Lane
A framework is outlined to assess Cepheids as potential cluster members from readily available photometric observations. A relationship is derived to estimate colour excess and dis…
