The potential broader complex linked to the key Cepheid SV Vul
Daniel Majaess, Ignacio Negueruela, Leonid N. Berdnikov +10
The paper determines a precise distance to the Cepheid variable SV Vul and its host cluster Alicante 13 using Gaia DR3 and UKIDSS data, and suggests that they may be part of a larg…

No country for old stars -Spectroscopic confirmation of the first intermediate-age RR Lyrae in the open cluster Trumpler 5
Valentina D'Orazi, Cecilia Mateu, Giuliano Iorio +13
RR Lyrae stars are widely considered tracers of ancient (greater than 10 Gyr), metal-poor stellar populations. However, recent kinematic and photometric studies suggest the existen…

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…
