A tale of three cataclysmic variables with distinct superhumps
Arti Joshi, Claus Tappert, Márcio Catelan +2
We present the TESS observations of CRTS J110014.7+131552, SDSS J093537.46+161950.8, and [PK2008] HalphaJ130559. Among them, a superoutburst is observed in CRTS J110014.7+131552 wh…
MUSE observations of V1425 Aql reveal an arc-shaped nova shell
L. Celedón, C. Tappert, L. Schmidtobreick +1
Nova shells are the remnants of a nova eruption in a cataclysmic variable system. By studying their geometry we can better understand the physical mechanisms that shape them during…
J-PLUS: The fraction of calcium white dwarfs along the cooling sequence
C. López-Sanjuan, P. -E. Tremblay, M. W. O'Brien +24
We used the Javalambre Photometric Local Universe Survey (J-PLUS) DR2 photometry in twelve optical bands over 2176 deg2 to estimate the fraction of white dwarfs with presence of Ca…
Unveiling the 3D structure of nova shells with MUSE -- The case of RR Pic
Lientur Celedón, Linda Schmidtobreick, Claus Tappert +1
Nova eruptions occur in cataclysmic variables when enough material has been accreted onto the surface of the white dwarf primary. As a consequence, the material that has been accum…
Introducing the Condor Array Telescope: IV. A possible nova super-remnant surrounding the putative recurrent nova KT Eridani
Michael M. Shara, Kenneth M. Lanzetta, James T. Garland +10
Just 10 recurrent novae (RNe) - which erupt repeatedly on timescales shorter than one century - are known in our Galaxy. The most extreme RN known (located in the Andromeda galaxy)…
The peculiar ejecta of the nova V1425 Aquilae
C. Tappert, L. Celedón, L. Schmidtobreick
Many important details of the mechanisms underlying the ejection of material during a (classical) nova eruption are still not understood. Here we present optical spectroscopy and n…
