DUERBECK - Galactic Novae References Catalog

Overview

This database table contains the Reference Catalog of Galactic Novae, Duerbeck, version 1990. It lists all objects known or believed to be novae at one time or other. Objects that were later found to be spurious have been omitted. Completeness was attempted only for novae and not for dwarf novae, X-ray novae, etc.

Parameters

Coord_Name
IRAS Scheme Coordinate Designation.

Name
Designation by coordinates (IRAS scheme).

RA
Right Ascension.

Dec
Declination.

LII
Galactic longitude.

BII
Galactic latitude.

Obs_Mag
Observed magnitude at outburst.

Uncert_Obs_Mag
Uncertainty note.

Obs_Band
Spectral region (p,j,v,r,i,B) of observed magnitude at outburst.

True_Mag
True maximum magnitude (based on extrapolation if deviating from observed magnitude at outburst).

Uncert_True_Mag
Uncertainty note.

True_Band
Spectral region of true maximum magnitude.

Min_Mag_Flag
'LL' for lower limit, otherwise blank.

Min_Mag
Minimum magnitude.

Uncert_Min_Mag
Uncertainly flag (':').

Min_Band
Spectral region of minimum magnitude.

Lcurve_Type
The type of light curve in the system of Duerbeck (PASP 93, 165 (1981)).

Decline_Time
Time of decline through 3 magnitudes.

Object_Type
Type of object.

      NA    = Fast nova, Time3-time smaller than 100 days,
              spectroscopically confirmed
      NB    = Slow nova, Time3-time larger or equal than 100 days,
              spectroscopically confirmed
      NC    = Extremely slow nova, typical time scale: decades
      N     = Nova; light curve too poorly known to establish speed class

The following additions are used:

      :     = nova, not confirmed by spectroscopic observations
      ?     = existence of object based on one photographic or a few
              independent visual observations
      ??    = existence based on no more than two visual observations

Other types of variability (objects once announced to be novae, but reclassified after more observations were obtained):

      NR    = Recurrent nova
      NL    = Novalike variable (inhomogeneous group)
      UG    = U Geminorum variable (dwarf nova)
      UGSS  = U Geminorum variable, SS Cyg subclass
      UGSU  = U Geminorum variable, SU UMa subclass
      UGZ   = U Geminorum variable, Z Cam subclass
      UGWZ  = U Geminorum variable, WZ Sge subclass (not yet official subclass)
      ZAND  = Symbiotic variable (Z And type)
      XND   = X-ray nova (transient) system consisting of a compact component
              and a dwarf or subgiant star with spectral type G to M
      M     = Mira star (long-period variable of large amplitude)
      UV    = UV Ceti type star (flare star)
      FU    = FU Ori type star (pre-main sequence)
      SDOR  = S Dor type star (Hubble-Sandage variable)

Outburst_Year
Year of outburst if known.

Nova
Nova designation.

NSV
NSV designation.

An
Provisional designation (AN).

Obs
Obs. designation.

DM_Number
BD-CoD Designation

HD
HD designation.

Other
Other designation.

Discoverer
Discoverer.

Class
The BROWSE object classification.
