The Nova Synthetic Data Base: A Principal Component/AI Analysis of Novae Synoptic Spectra
Bruno C. Santos, Marcos P. Diaz, Larissa Takeda
The Nova Synthetic Data Base (NSDB) is presented as the first publicly available database of synthetic spectra for classical nova shells, spanning an unprecedented range of physica…
VLT VIMOS Integral Field Spectroscopy of the nova remnant FH Ser
M. A. Guerrero, E. Santamaria, L. Takeda +4
FH Ser experienced a slow classical nova outburst in February 1970 that was the first one observed at UV, optical, and IR wavelengths. Its nova remnant is elliptical in shape, with…
A two-component clumpy model for the shell evolution of classical novae: the case of V5668 Sgr
Zulema Abraham, Larissa Takeda, Pedro P. B. Beaklini +4
The shell of the classical nova V5668 Sgr was resolved by ALMA at the frequency of 230 GHz 927 days after eruption, showing that most of the continuum bremsstrahlung emission origi…
Optical and NIR data and modelling of nova V5668 Sgr
L. Takeda, M. Diaz, R. D. Campbell +4
We present HST optical images, Keck-OSIRIS NIR IFS data cubes and Keck-NIRC2 NIR images of nova V5668 Sgr from 2016 to 2019. The observations indicate enhanced emission at the pola…
Imaging and analysis of neon nova V382 Vel shell
Larissa Takeda, Marcos Diaz
We present the detection and imaging of the spatially resolved shell of nova V382 Vel with SOAR adaptive optics module (SAM). The shell was observed in narrow band filters H and…
The structure of a recent nova shell as observed by ALMA
Marcos P. Diaz, Zulema Abraham, Valério A. R. M. Ribeiro +2
High resolution ALMA observations of the recent (2.52 yrs old) shell of Nova V5668 Sgr (2015) show a highly structured ionised gas distribution with small (10 cm) clumps. Th…
3D photoionization models of nova V723 Cas
L. Takeda, M. Diaz, R. Campbell +1
We present modeling and analysis of the ejecta of nova V723 Cas based on spatially resolved IR spectroscopic data from Keck-OSIRIS, with LGSAO (adaptive optics module). The 3D phot…
A search and modeling of peculiar narrow transient line components in novae spectra
Larissa Takeda, Marcos Diaz
In this paper we discuss the formation of peculiar narrow emission line components observed in the spectra of a few novae. We aim to identify the physical source responsible for tr…
The spectral evolution and ejecta of recurrent nova U Sco in the 2010 outburst
M. P. Diaz, R. E. Williams, G. J. Luna +2
Synoptic spectroscopic observations of the U Sco 2010 outburst from maximum light to quiescence as well as a contemporaneous X-ray observation are presented and analyzed. The X-ray…
