Information on Service 'The LIFE Target Star Database LIFETD'

[Use this service from your browser]

Further access options are discussed below

The LIFE Target Star Database contains information useful for the planned LIFE mission (mid-ir, nulling interferometer in space). It characterizes possible target systems including information about stellar, planetary and disk properties. The data itself is mainly a collection from different other catalogs.

Note that LIFE's target database is living data. The content – and to some extent even structure – of these tables may change at any time without prior warning.

Service Documentation

Please note that the Simple Cone Search service is intended for very casual use only. The primary interface to the LIFE target database is through TAP; see also the query examples for LIFE-TD.

Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

NameTable Head DescriptionUnitUCD
DEC Delta (ICRS) Declination (ICRS decimal) deg pos.eq.dec
hscs_pos Position/Name Coordinates (as h m s, d m s or decimal degrees), or SIMBAD-resolvable object N/A N/A
hscs_sr Search radius Search radius in arcminutes N/A N/A
maxrec Match limit Maximum number of records returned. Pass 0 to retrieve service parameters. N/A N/A
planet_mass Planet Mass Mass 'jupiterMass' phys.mass
planet_name Planet Name of the planet N/A meta.id;meta.main
RA Alpha (ICRS) Right Ascension (ICRS decimal) deg pos.eq.ra
responseformat Output Format File format requested for output. N/A meta.code.mime
SR Search Radius Search radius deg N/A
verb Verbosity Exhaustiveness of column selection. VERB=1 only returns the most important columns, VERB=2 selects the columns deemed useful to the average user, VERB=3 returns a table with all available columns. N/A N/A

Default Output Fields

The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

NameTable Head DescriptionUnitUCD
_r Dist. Distance to cone center deg pos.distance
dec Dec (ICRS) Declination deg pos.eq.dec;meta.main
dist Dist Object distance. pc pos.distance
planet_mass Planet Mass Mass 'jupiterMass' phys.mass
planet_mass_error Err. Mass Mass error 'jupiterMass' stat.error;phys.mass
planet_name Planet Name of the planet N/A meta.id;meta.main
ra RA (ICRS) Right Ascension deg pos.eq.ra;meta.main
star_name Host Star Name of the planet's host star N/A meta.id

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.

NameTable Head DescriptionUnitUCD Verb. Level
star_name Host Star Name of the planet's host star N/A meta.id 5
planet_name Planet Name of the planet N/A meta.id;meta.main 5
ra RA (ICRS) Right Ascension deg pos.eq.ra;meta.main 5
dec Dec (ICRS) Declination deg pos.eq.dec;meta.main 5
dist Dist Object distance. pc pos.distance 5
planet_mass Planet Mass Mass 'jupiterMass' phys.mass 5
planet_mass_error Err. Mass Mass error 'jupiterMass' stat.error;phys.mass 5
