Optical Time-Series Photometry of the Symbiotic Nova V1835 Aquilae

Robert V. Caddy, Andrew C. Layden, Daniel E. Reichart +7

We present time-series CCD photometry in the passbands of the recently identified symbiotic nova V1835 Aquilae (NSV 11749) over an interval of 5.1 years with 7-14 day cadenc…

Refining the prediction for OJ 287 next impact flare arrival epoch

Mauri J. Valtonen, Staszek Zola, A. Gopakumar +23

The bright blazar OJ~287 routinely parades high brightness bremsstrahlung flares which are explained as being a result of a secondary supermassive black hole (SMBH) impacting the a…

Circumstellar Medium Interaction in SN 2018lab, A Low-Luminosity II-P Supernova observed with TESS

Jeniveve Pearson, Griffin Hosseinzadeh, David J. Sand +21

We present photometric and spectroscopic data of SN 2018lab, a low luminosity type IIP supernova (LLSN) with a V-band peak luminosity of mag. SN 2018lab was discovere…

Panchromatic evolution of three luminous red novae: Forbidden hugs in pandemic times -- IV

A. Pastorello, G. Valerin, M. Fraser +77

We present photometric and spectroscopic data on three extragalactic luminous red novae (LRNe): AT2018bwo, AT2021afy, and AT2021blu. AT2018bwo was discovered in NGC45 (at 6.8 Mpc)…

Early Lightcurves of Type Ia Supernovae are Consistent with Nondegenerate Progenitor Companions

J. Burke, D. A. Howell, D. J. Sand +16

If Type Ia supernovae (SNe~Ia) result from a white dwarf being ignited by Roche lobe overflow from a nondegenerate companion, then as the supernova explosion runs into the companio…

The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission

Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40

SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…

Host galaxy magnitude of OJ 287 from its colours at minimum light

Mauri J. Valtonen, Lankeswar Dey, S. Zola +54

OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of magnitude. The only exception to this may be at minimum ligh…

Constraining the Progenitor System of the Type Ia Supernova 2021aefx

Griffin Hosseinzadeh, David J. Sand, Peter Lundqvist +25

We present high-cadence optical and ultraviolet light curves of the normal Type Ia supernova (SN) 2021aefx, which shows an early bump during the first two days of observation. This…

Weak Mass Loss from the Red Supergiant Progenitor of the Type II SN 2021yja

Griffin Hosseinzadeh, Charles D. Kilpatrick, Yize Dong +56

We present high-cadence optical, ultraviolet (UV), and near-infrared data of the nearby ( Mpc) Type II supernova (SN) 2021yja. Many Type II SNe show signs of interactio…

Infant-phase reddening by surface Fe-peak elements in a normal Type Ia Supernova

Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +41

Type Ia Supernovae are thermonuclear explosions of white dwarf stars. They play a central role in the chemical evolution of the Universe and are an important measure of cosmologica…

Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations

J. Marques Oliveira, B. Sicardy, A. R. Gomes-Júnior +234

A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of…
