A 70 pc-Diameter Nova Super-remnant Surrounding the Recurrent Nova RS Ophiuchi

Michael M. Shara, Kenneth M. Lanzetta, Alexandra Masegian +9

Recurrent novae undergo thermonuclear-powered eruptions separated by less than 100 years, enabled by subgiant or red giant donors transferring hydrogen-rich matter at very high rat…

Ultraviolet spectroscopy of the black hole X-ray binary MAXI J1820+070 across a state transition

Maria Georganti, Christian Knigge, Noel Castro Segura +8

We present ultraviolet (UV) spectroscopic observations covering three distinct accretion states of the low-mass X-ray binary (LMXB) MAXI J1820+070: the luminous hard state, a hard-…

Introducing the Condor Array Telescope: III. The expansion and age of the shell of the dwarf nova Z Camelopardalis, and detection of a second, larger shell

Michael M. Shara, Kenneth M. Lanzetta, James T. Garland +7

The existence of a vast nova shell surrounding the prototypical dwarf nova Z Camelopardalis (Z Cam) proves that some old novae undergo metamorphosis to appear as dwarf novae thousa…

Speckle Imaging of Gamma2 Velorum: The Inner Wind Possibly Resolved

Michael M. Shara, Steve B. Howell, Elise Furlan +3

Accurately quantifying the rates dM/dt at which massive stars lose mass is essential to any understanding of their evolution. All dM/dt estimates to date assume wind clumping facto…

A 9-Month Hubble Space Telescope Near-UV Survey of M87. I. Light and Color Curves of 94 Novae, and a Re-determination of the Nova Rate

Michael M. Shara, Alec M. Lessing, Rebekah Hounsell +10

M87 has been monitored with a cadence of 5 days over a 9 month-long span through the near-ultraviolet (NUV:F275W) and optical (F606W) filters of the Wide Field Camera 3 (WFC3) of t…

No plateau observed in late-time near-infrared observations of the underluminous Type Ia supernova 2021qvv

O. Graur, E. Padilla Gonzalez, J. Burke +23

Near-infrared (NIR) observations of normal Type Ia supernovae (SNe Ia) obtained between 150 to 500 d past maximum light reveal the existence of an extended plateau. Here, we presen…
