SN 2024afyu interpreted as a Pair Instability Supernova
P. J. Pessi, S. Barmentloo, Ł. Wyrzykowski +63
Pair-instability supernovae (PISNe) are the predicted explosions of very massive stars triggered by electron-positron pair production. Numerous transients have been proposed as PIS…
The Progenitor of the Type II-Plateau SN 2025pht in NGC 1637: The Dustiest, Most Luminous Red Supergiant So Far?
Schuyler D. Van Dyk, Tamas Szalai, Gagandeep S. Anand +14
We provide a characterization of the red supergiant (RSG) progenitor candidate for the nearby Type II-plateau supernova (SN) 2025pht in NGC 1637. The star was first detectable in 2…
Follow-up on three poorly studied AM CVn stars
Amornrat Aungwerojwit, Boris T. Gaensicke, E. Breedt +12
We report follow-up observations of three poorly studied AM CVn-type binaries: CRTS CSS150211 J091017-200813, NSV1440, and SDSSJ183131.63+420220.2. Analysing time-series photometry…
PM 1-322: new variable planetary nebula
E. Paunzen, K. Bernhard, J. Budaj +4
Spectra of planetary nebulae (PNe) are characterised by strong forbidden emission lines and often also by an infrared (IR) excess. A few PNe show dust obscuration events and/or har…
First results on RR Lyrae stars with the TESS space telescope: untangling the connections between mode content, colors and distances
László Molnár, Attila Bódi, András Pál +25
The TESS space telescope is collecting continuous, high-precision optical photometry of stars throughout the sky, including thousands of RR Lyrae stars. In this paper, we present r…
The 2019 outburst of the 2005 classical nova V1047 Cen: a record breaking dwarf nova outburst or a new phenomenon?
E. Aydi, K. V. Sokolovsky, J. S. Bright +28
We present a detailed study of the 2019 outburst of the cataclysmic variable V1047~Cen, which hosted a classical nova eruption in 2005. The peculiar outburst occurred 14 years afte…
ASASSN-21co: A detached eclipsing binary with an 11.9 year period
D. M. Rowan, K. Z. Stanek, Z. Way +10
We use ASAS V-band and ASAS-SN g-band observations to model the long-period detached eclipsing binary ASASSN-21co. ASAS observations show an eclipse of depth V ~ 0.6 mag in April o…
A search for transiting companions in the J1407 (V1400 Cen) system
S. Barmentloo, C. Dik, M. A. Kenworthy +5
In 2007, the young star 1SWASP J140747.93-394542.6 (V1400 Cen) underwent a complex series of deep eclipses over 56 days. This was attributed to the transit of a ring system filling…
ROAD and K2 photometry of V348 Sgr: probing the pulsation dust connection
C. Simon Jeffery, F. -Josch Hambsch
V348 Sgr is simultaneously an active hot R Coronae Borealis (RCB) variable, a peculiar extreme helium star, and the hydrogen-deficient central star of a planetary nebula. Explainin…
Extensive Photometry of V1838 Aql during the 2013 Superoutburst
J. Echevarría, E. de Miguel, J. V. Hernández Santisteban +15
We present an in-depth photometric study of the 2013 superoutburst of the recently discovered cataclysmic variable V1838 Aql and subsequent photometry near its quiescent state. A c…
Photometric long-term variations and superhump occurrence in the Classical Nova RR Pictoris
I. Fuentes-Morales, N. Vogt, C. Tappert +3
We present an analysis of all available time-resolved photometry from the literature and new light curves obtained in 2013-2014 for the old nova RR Pictoris. The well-known hump li…
Near-infrared and optical studies of the highly obscured nova V1831 Aquilae (Nova Aquilae 2015)
D. P. K. Banerjee, Mudit K. Srivastava, N. M. Ashok +4
Near Infrared (NIR) and optical photometry and spectroscopy are presented for the nova V1831 Aquilae, covering the early decline and dust forming phases during the first 90 d…
The beta Pictoris association: Catalog of photometric rotational periods of low-mass members and candidate members
S. Messina, M. Millward, A. Buccino +19
We intended to compile the most complete catalog of bona fide members and candidate members of the beta Pictoris association, and to measure their rotation periods and basic proper…
A radio pulsing white dwarf binary star
T. R. Marsh, B. T. Gänsicke, S. Hümmerich +23
White dwarfs are compact stars, similar in size to Earth but ~200,000 times more massive. Isolated white dwarfs emit most of their power from ultraviolet to near-infrared wavelengt…
Mass and period limits on the ringed companion transiting the young star J1407
M. A. Kenworthy, S. Lacour, A. Kraus +11
The young (~16 Myr) pre-main-sequence star in Sco-Cen 1SWASP J140747.93-394542.6, hereafter referred to as J1407, underwent a deep eclipse in 2007 April, bracketed by several shall…
