Planetary Nebula Central Stars as Tracers of Planetary Nebula-Star Cluster Associations in the Galaxy
Vasiliki Fragkou, Luis Lomelí-Núñez, Dante Minniti +2
Planetary nebulae (PNe) that are physically associated with star clusters are rare but crucial for stellar evolution studies because they allow their initial and final stellar prop…
Ultracool and Brown Dwarf Candidates Identified via CatWISE-2MASS-Gaia DR3
Daniel Majaess, Dante Minniti, Matias Gomez +2
Ultracool and brown dwarf candidates ( pc, ) were identified via multiband and astrometric data from CatWISE (), 2MASS (), and…
The potential broader complex linked to the key Cepheid SV Vul
Daniel Majaess, Ignacio Negueruela, Leonid N. Berdnikov +10
A new distance was established to the Cepheid SV Vul () and its host cluster Alicante 13, and is tied in part to deeper UKIDSS-DR6 photometry and Gaia DR3 observatio…
Near-infrared photometry of the central stars of planetary nebulae with the VVVX survey
Dante Minniti, Vasiliki Fragkou, Javier Alonso-García +2
Achieving accurate photometric characterizations of central stars of planetary nebulae (CSPNe) toward the galactic plane is significantly hindered by the high levels of interstella…
VVV-WIT-13: an eruptive young star with cool molecular features
Zhen Guo, Philip Lucas, Sergey N. Yurchenko +27
Here we investigate an infrared eruptive source, identified from the decade-long VISTA Variables in the Via Lactea survey (VVV). We named this target after a group of variable sour…
The Gaia parallax discrepancy for the cluster Pismis 19, and separating Scutis from Cepheids
Daniel Majaess, Charles J. Bonatto, David G. Turner +10
Pre-Gaia distances for the open cluster Pismis 19 disagree with Gaia parallaxes. A 2MASS red clump distance was therefore established for Pismis 19 ( kpc), whic…
The Valuable Long-period Cluster Cepheid KQ Scorpii and other Calibration Candidates
Daniel Majaess, David G. Turner, Dante Minniti +2
The classical Cepheid KQ Sco is a valuable anchor for the distance scale because of its long pulsation period () and evidence implying membership in the open cluster…
A Benchmark White Dwarf-Ultracool Dwarf Wide Field Binary
Thiago Ferreira, Roberto K. Saito, Dante Minniti +8
We present the discovery and multi-wavelength characterisation of VVV J1438-6158 AB, a new field wide-binary system consisting of a 4.6(+5.5-2.4) Gyr and Teff = 9500+/-125 K DA whi…
VVV-WIT-12 and its fashionable nebula: a four year long period Young Stellar Object with a light echo?
Roberto K. Saito, Bringfried Stecklum, Dante Minniti +7
We report the serendipitous discovery of VVV-WIT-12, an unusual variable source that seems to induce variability in its surrounding nebula. The source belongs to the rare objects t…
Extreme infrared variables from UKIDSS - II. an end-of-survey catalogue of eruptive YSOs and unusual stars
P. W. Lucas, L. C. Smith, C. Contreras Pena +7
We present a catalogue of 618 high amplitude infrared variable stars (1 < DeltaK < 5 mag) detected by the two widely separated epochs of 2.2 um data in the UKIDSS Galactic plane su…
