# Gumala

Gumala is an F8V yellow-white main-sequence [star](https://spacecatalog.org/stars) in the constellation [Sagittarius](https://spacecatalog.org/constellation/sagittarius), 89.85 ly from Earth, shining at apparent magnitude 6.25 (V). Other catalogues list it as GJ 749, HD 179949 and HIP 94645, among 7 designations in total.

## At a glance

- **WHAT IT IS:** Yellow-white main-sequence star
- **HOW FAR:** 89.85 ly — The light arriving now left it that long ago.
- **HOW BRIGHT (V):** 6.25 — Bright enough for the naked eye, under a sky dark enough.
- **WHERE TO LOOK:** [Sagittarius](https://spacecatalog.org/constellation/sagittarius) — The patch of sky it sits in, as seen from Earth.

## Properties

| Quantity | Value |
| --- | --- |
| CLASS | F8V yellow-white main-sequence star |
| MASS | 1.11 M☉ — Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: Gaia's classifier calls the source a binary, which GSP-Phot fitted as one star |
| DISTANCE FROM EARTH | 89.85 ly — by parallax |
| APPARENT MAGNITUDE (V) | 6.25 |
| ABSOLUTE MAGNITUDE (V) | 4.05 |
| CONSTELLATION | Sagittarius |
| RIGHT ASCENSION (J2000) | 19h 15m 33.2s |
| DECLINATION (J2000) | −24° 10′ 45.7″ |

## Catalogue data

### WHAT KIND OF THING IT IS

What the object is in itself, rather than how it happens to look from here.

| Field | Value |
| --- | --- |
| Spectral type | F8V |
| Surface temperature | 6068 K |
| Luminosity (visual) | 2.0893 L☉ |
| Luminosity (bolometric) | 1.9838 L☉ |
| Radius | 1.279 R☉ |
| Mass | 1.111 M☉ |
| Surface gravity (log g) | 4.201 |
| Metallicity (\[Fe/H\]) | 0.2 |
| Age | 4.83×10⁹ years |
| Variability | BY Draconis spotted rotating variable |
| Variability type (GCVS) | BY |
| Variability period | 7.06546 days |

### HOW BRIGHT IT IS

What the light adds up to, measured through one filter at a time. A magnitude is a brightness on a backwards scale — the smaller the number, the brighter the object.

| Field | Value |
| --- | --- |
| Colour index (B−V) | 0.548 |
| Variable magnitude, brightest | 6.24 |
| Variable magnitude, faintest | 6.26 |

### WHERE IT IS AND HOW IT MOVES

Position, motion across the sky and the size it covers on it. These are measurements of the object as seen from here, so every one of them depends on where here is.

| Field | Value |
| --- | --- |
| Proper motion (RA) | 114.78 mas/yr |
| Proper motion (Dec) | −101.81 mas/yr |
| Radial velocity | −26 km/s |

### OTHER NAMES AND NUMBERS

The identifiers other catalogues file this object under, for anyone joining this data to theirs.

| Field | Value |
| --- | --- |
| Variable-star designation | V5652 Sgr |
| Wikidata item | Q1280098 |
| Wikipedia article | HD 179949 |

### WHERE THESE FIGURES CAME FROM

Which catalogue, paper or model each of the fields above was read from, where the source named one.

| Field | Value |
| --- | --- |
| Spectral type from | SIMBAD (1988MSS...C04....0H, quality C) |
| Stellar parameters from | Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: Gaia's classifier calls the source a binary, which GSP-Phot fitted as one star |
| Metallicity from | Median of 20 spectroscopic determinations in 23 papers, compiled from the literature (PASTEL, Soubiran+ 2016); the error bar is the scatter between them |
